Left panel: Nuclear modification factors of non-prompt $\Dzero$ and $\Dplus$ mesons measured in p--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV compared with the measurement of non-prompt J/$\psi$ at midrapidity~, and the measurements of non-prompt J/$\psi$ and $\rm B^{+}$ mesons at forward and backward rapidity~. The results are also compared with B-meson \RpPb calculations using different nPDF sets~. Right panel: \pt-integrated nuclear modification factor of prompt and non-prompt $\Dzero$ mesons measured in p--Pb and Pb--Pb collisions at \snn = 5.02 TeV~. Statistical (bars) and systematic (boxes) uncertainties are shown. Extrapolation uncertainties of non-prompt \Dzero mesons in p--Pb and Pb--Pb collisions are shown separately as shaded bands.
