Recently, we have shown that the values of the effective axial-vector current coupling constants ($g_A^\\textrm{eff}$) for the $0\\nu\\beta\\beta$ and the two-neutrino double-$\\beta$ decays are close. This striking result was obtained for the first time by including vertex corrections and two-body currents in these matrix elements.
