Nuclear modification factor $\RpPb$ in p-Pb collisions at $\snn = 5.02$ TeV for the $\phi$-meson as a function of $\pt$, in the backward (left) and forward (right) rapidity regions considered in the analysis. Error bars and boxes represent statistical and bin-to-bin uncorrelated systematic uncertainties, respectively. The blue box on the left represents the bin-to-bin correlated systematic uncertainty, see Table 7.
