Nuclear modification factor of muons from heavy-flavour hadron decays as a function of $\pt$ for p-Pb collisions at $\sqrt {s_{\rm NN}}$ = 5.02 TeV at forward rapidity ($2.03< y_{\rm cms}< 3.53$, top) and backward rapidity ($-4.46< y_{\rm cms}< -2.96$, bottom) compared to model predictions [70-72] Statistical uncertainties (bars), systematic uncertainties (open boxes), and normalisation uncertainties (filled box at $R_{\rm pPb}^{\mu^\pm \leftarrow {\rm HF}}$ = 1) are shown. Filled (open) symbols refer to the pp reference obtained from an energy and rapidity scaling to the measurement at $\sqrt s$ = 7 TeV (an extrapolation based on FONLL calculations).
