By using high magnetic field data to estimate the background conductivity,Rullier-Albenque and coworkers have recently published [Phys.Rev.B 84, 014522(2011)] experimental evidence that the in-plane paraconductivity in cuprates isalmost independent of doping. In this Comment we also show that, in contrastwith their claims, these useful data may be explained at a quantitative levelin terms of the Gaussian-Ginzburg-Landau approach for layered superconductors,extended by Carballeira and coworkers to high reduced-temperatures byintroducing a total-energy cutoff [Phys.Rev.B 63, 144515 (2001)]. Whencombined, these two conclusions further suggest that the paraconductivity incuprates is conventional, i.e., associated with fluctuating superconductingpairs above the mean-field critical temperature.
