    Assessing the practical arguments for randomisation in clinical trialsManuscript (preprint) (Other academic)
    Abstract [en]

    Practical arguments for randomisation are arguments with no necessary connections to theoretical frameworks like null hypothesis testing or causal inferences. Four common practical arguments in the context of clinical trials are distinguished and assessed: (1) Randomisation contributes to allocation concealment. (2) Randomisation contributes to the baseline balance of treatment groups. (3) Randomisation decreases self-selection bias. (4) Randomisation removes allocation bias. Argument (1) is rejected, but (2), (3), and (4) are all approved. However, (2) is approved only in a weak form that relates exclusively to simple randomisation and to particular circumstances. This is so because random balance is rarely the best balance that can be achieved. It is judged that (4) may be the strongest single argument.

    Assessing the theoretical arguments for randomisation in clinical trialsManuscript (preprint) (Other academic)
    Abstract [en]

    There are three main arguments for randomisation that connect inseparably to theoretical concepts: (1) Randomisation is needed for performing null hypothesis testing. (2) Randomisation is needed for plausible causal inferences from treatment to effect. (3) Randomisation is epistemically acceptable and computationally convenient in a Bayesian setting. A critical scrutiny of these arguments shows that only (1) is clearly tenable in the context of clinical trials, but then only in a weaker version according to which randomisation is sufficient, but not necessary, for null hypothesis testing conditions to be fulfilled. As for (2), it is argued that randomisation only provides weak reasons for drawing causal inferences in the context of real (as opposed to theoretically ideal but unrealistic) clinical trials. Argument (3) is weak because it is controversial among Bayesians, and because formally Bayesian analyses of trial results are rarely asked for.

    Negative mechanistic reasoning in medical intervention assessment2015In: Theoretical Medicine and Bioethics, ISSN 1386-7415, E-ISSN 1573-0980, Vol. 36, no 6, p. 425-437Article in journal (Refereed)
    Abstract [en]

    Traditionally, mechanistic reasoning has been assigned a negligible role in standard EBM (evidence-based medicine) literature, although some recent authors have argued for an upgrading. Even so, mechanistic reasoning that has received attention has almost exclusively been positive – both in an epistemic sense of claiming that there is a mechanistic chain and in a health-related sense of there being claimed benefits for the patient. Negative mechanistic reasoning has been neglected, both in the epistemic and in the health-related sense. I distinguish three main types of negative mechanistic reasoning and subsume them under a new definition of mechanistic reasoning in the context of assessing medical interventions. This definition is wider than a previous suggestion in the literature. Each negative type corresponds to a range of evidential strengths, and it is argued that there are differences with respect to the typical evidential strengths. The variety of negative mechanistic reasoning should be acknowledged in EBM, and presents a serious challenge to proponents of so-called medical hierarchies of evidence.

    Om valkretsstorlekars spärreffekterManuscript (preprint) (Other (popular science, discussion, etc.))
    Abstract [en]

    In the absence of formal thresholds for representation, the constituency size will determine the effective threshold. In Swedish municipality elections there are (as of 2014) no formal thresholds, but the constituency sizes vary considerably. This note mainly presents the two mathematical formulas of interest for the calculation of effective thresholds. The voting share needed to get one seat under maximally charitable conditions (with respect to the distribution of votes among the other parties) is given by equation (7), where d is the first divisor (currently set to 1.4 in the Swedish system), M is the number of seats, and n is the number of parties. The voting share needed to be guaranteed to have one seat is given by equation (13). There is a threshold in between these extremes, a threshold at which there is a 50 % probability of winning one seat and a 50 % probability of winning none. For sufficiently large values of M, it is reasonable to believe that equation (5) provides a good approximation for the 50 % probability threshold.

    On the Meaning of Medical Evidence Hierarchies2021In: Philosophy of Medicine, ISSN 2692-3963, Vol. 2, no 1Article in journal (Refereed)
    Abstract [en]

    Evidence hierarchies are lists of investigative strategies ordered with regard to the claimed strength of evidence. They have been used for a couple of decades within EBM, particularly for the assessment of evidence for treatment recommendations, but they remain controversial. An under-investigated question, from critics and adherents of evidence hierarchies alike, is what the order in the hierarchy means. Four interpretations of the order are distinguished and discussed. The two most credible ones are, roughly expressed, "typically stronger" or "ideally stronger". The well-known GRADE framework seems to assume some "typically stronger" reading. Unfortunately, even if the interpretation of an evidence hierarchy were established, hierarchies appear to be rather unhelpful for the task of evidence aggregation. Nevertheless, a specification of the intended order relation may be helpful in sorting out disagreements in debates on evidence hierarchies. Therefore, proponents and adversaries of evidence hierarchies are equally obliged to specify the order interpretations they are assuming in their arguments.

    Philosophical Aspects of Evidence and Methodology in Medicine2021Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The thesis consists of an introduction and five papers. The introduction gives a brief historical survey of empirical investigations into the effectiveness of medicinal interventions, as well as surveys of the concept of evidence and of the history and philosophy of experiments. The main ideas of the EBM (evidence-based medicine) movement are also presented.

    Paper I: Concerns have been raised that clinical trials do not offer reliable evidence for some types of treatment, in particular for highly individualised treatments, for example traditional homeopathy. With respect to individualised treatments, it is argued that such concerns are unfounded. There are two minimal conditions related to the nature of the treatments that must be fulfilled for evaluability in a clinical trial, namely (1) the proper distinction of treatment groups and (2) the elimination of confounding variables or variations. These conditions do not preclude the testing of individualised medicine.

    Paper II: Traditionally, mechanistic reasoning has been assigned a negligible role in the EBM literature. When discussed, mechanistic reasoning has almost exclusively been positive – both in an epistemic sense of claiming that there is a mechanistic chain and in a health-related sense of there being claimed benefits for the patient. Negative mechanistic reasoning has been neglected. I distinguish three main types of negative mechanistic reasoning and subsume them under a new definition. One of the three distinguished types, which is negative only in the health-related sense, has a corresponding positive counterpart, whereas the other two, which are epistemically negative, do not have such counterparts, at least not that are particularly interesting as evidence. Accounting for negative mechanistic reasoning in EBM is therefore partly different from accounting for positive mechanistic reasoning.

    Paper III: Evidence hierarchies are lists of investigative strategies ordered with regard to the claimed strength of evidence. They have been used for a couple of decades within EBM, particularly for the assessment of evidence for treatment recommendations, but they remain controversial. An under-investigated question is what the order in the hierarchy means. Four interpretations of the order are distinguished and discussed. The two most credible ones are, in rough terms, “typically stronger” and “ideally stronger”. The GRADE framework seems to be based on the “typically stronger” reading. Even if the interpretation of an evidence hierarchy were established, hierarchies appear to be rather unhelpful for the task of evidence aggregation. However, specifying the intended order relation may help sort out disagreements.

    Paper IV: There are three main arguments for randomisation that connect inseparably to theoretical concepts: (1) Randomisation is useful for performing null hypothesis testing. (2) Randomisation is needed for plausible causal inferences from treatment to effect. (3) Randomisation is acceptable and computationally convenient in a Bayesian setting.

Four common practical arguments in the context of clinical trials are distinguished and assessed: (1) Randomisation contributes to allocation concealment. (2) Randomisation contributes to the baseline balance of treatment groups. (3) Randomisation decreases self-selection bias. (4) Randomisation removes allocation bias. Argument (1) is rejected. Arguments (3) and (4) are approved. Argument (2) is rejected if it is formulated so as to be independent from (3) and (4), but it is true that randomisation contributes to balance through the mechanisms mentioned in (3) and (4). It is judged that (4) may be the strongest single argument.

    Philosophical Issues in Medical Intervention Research2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The thesis consists of an introduction and two papers. In the introduction a brief historical survey of empirical investigations into the effectiveness of medicinal interventions is given. Also, the main ideas of the EBM (evidence-based medicine) movement are presented. Both included papers can be viewed as investigations into the reasonableness of EBM and its hierarchies of evidence.

    Paper I: Typically, in a clinical trial patients with specified symptoms are given either of two or more predetermined treatments. Health endpoints in these groups are then compared using statistical methods. Concerns have been raised, not least from adherents of so-called alternative medicine, that clinical trials do not offer reliable evidence for some types of treatment, in particular for highly individualized treatments, for example traditional homeopathy. It is argued that such concerns are unfounded. There are two minimal conditions related to the nature of the treatments that must be fulfilled for evaluability in a clinical trial, namely (1) the proper distinction of the two treatment groups and (2) the elimination of confounding variables or variations. These are delineated, and a few misunderstandings are corrected. It is concluded that the conditions do not preclude the testing of alternative medicine, whether individualized or not.

    Paper II: Traditionally, mechanistic reasoning has been assigned a negligible role in standard EBM literature, although some recent authors have argued for an upgrading. Even so, mechanistic reasoning that has received attention has almost exclusively been positive -- both in an epistemic sense of claiming that there is a mechanistic chain and in a health-related sense of there being claimed benefits for the patient. Negative mechanistic reasoning has been neglected, both in the epistemic and in the health-related sense. I distinguish three main types of negative mechanistic reasoning and subsume them under a new definition of mechanistic reasoning in the context of assessing medical interventions. Although this definition is wider than a previous suggestion in the literature, there are still other instances of reasoning that concern mechanisms but do not (and should not) count as mechanistic reasoning. One of the three distinguished types, which is negative only in the health-related sense, has a corresponding positive counterpart, whereas the other two, which are epistemically negative, do not have such counterparts, at least not that are particularly interesting as evidence. Accounting for negative mechanistic reasoning in EBM is therefore partly different from accounting for positive mechanistic reasoning.

    Abstract [sv]

    Sinnelagsetik förekommer frekvent i etikundervisningen inom religionsämnet på gymnasiet, men begreppet är nästan okänt i universitetsundervisning inom etik. Här granskas varifrån termen kommer, vad den har betytt historiskt samt vad den betyder i nutida gymnasieundervisning. Slutsatsen blir att undervisningen om sinnelagsetik i gymnasiet är tvivelaktig och bör utgå.
