In this letter, we exploit the potential relevance of the analysis of Palanque-Delabrouille et al. [JCAP 1502, 045 (2015)] to the neutrinoless double beta decay (0{\\nu}{\\beta}{\\beta}) search. This analysis indicates small values for the lightest neutrino mass, since the authors find {\\Sigma} < 84 meV at 1{\\sigma} C. L., and provides a 1{\\sigma} preference for the normal hierarchy.
