Average $\Dzero$, $\Dplus$ and $\Dstar$ meson nuclear modification factors as a function of $\pt$ in the 0-20%, 20-40%, 40-60% and 60-100% centrality classes selected with the ZNA estimator The vertical error bars and the empty boxes represent the statistical and systematic uncertainties, respectively. The colour-filled boxes at $\QpPb=1$ represent the normalisation uncertainties Symbols are displaced from the bin centre for clarity
