The observation of nonzero voltage transverse to the current flow, in zero magnetic field, is a sensitive indication of the nematic order in cuprate superconductors. But this effect should be carefully identified and differentiated from various conceivable experimental artifacts. Here we discuss in detail the five types of artifacts commonly encountered in transport experiments and explain how we rule out these possibilities by decisive experimental evidence.
