  By measuring the in-plane resistivity as a function of temperature and
magnetic field in overdoped La2-xSrxCuO4 (LSCO) superconductors, in a recent
Letter Rourke et al. [Nature Physics 7, 455 (2011)] have addressed the long
standing but still open issue of the interplay between pseudogap and
superconducting fluctuations in cuprates. Unfortunately, these authors have
analyzed their interesting measurements without taking into account the
unavoidable inhomogeneities of the zero-field critical temperature Tc0
associated with the random distribution of the Sr ions, in spite of the
different works on this issue in the same compounds. Here we will show that
such a shortcoming invalidates most of the conclusions of Rourke et al.
