Analysis of the in-plane resistivity of a Tl2Ba2CaCu2O8+delta thin film and of several oxygen-deficient YBa2Cu3O7-delta single crystals in magnetic fields 0less than or equal toBless than or equal to12 T applied along the crystallographic c axis were performed to study the resistive transition into the glassy state. The transition curves were scaled according to a modified model for the vortex-liquid resistivity, finding good scaling only for fields below a certain value B-0, consistent with the field-induced crossover between a three-dimensional and quasi-two-dimensional regime of the vortex fluctuations reported in several works. This indicates that for low fields the vortex state is in fact three dimensional and provides further support to a coherent description of the vortex-liquid resisitivity.
