The $p_{\rm T}$-integrated and to $p_{\rm T}>0$ extrapolated $\Lambda_{\rm c}^+/{\rm D^0}$ ratios in central and mid-central Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV compared to the same ratio at pp and p$-$Pb and Au$-$Au multiplicities. Predictions from theoretical calculations are shown as well.
