Addendum to: Quasiparticle random phase approximation uncertainties and their correlations in the analysis of 0νββ decay

In a previous article [A. Faessler et al., Phys. Rev. D 79, 053001 (2009)], we estimated the correlated uncertainties associated to the nuclear matrix elements of neutrinoless double beta decay ($0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$) within the quasiparticle random phase approximation. Such estimates encompass recent independent calculations of nuclear matrix elements and can thus still provide a fair representation of the nuclear model uncertainties. In this context, we compare the claim of $0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$ decay in $^{76}\mathrm{Ge}$ with recent negative results in $^{136}\mathrm{Xe}$ and in other nuclei, and we infer the lifetime ranges allowed or excluded at 90% C.L. We also highlight some issues that should be addressed in order to properly compare and combine results coming from different $0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$ candidate nuclei.
