The nuclear modification factor of charged particles as a function of transverse momentum, measured in minimum-bias (NSD) p-Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV in two pseudorapidity ranges, $|\eta_{\mathrm{cms}}|< 0.3$ and $-1.3< \eta_{\mathrm{cms}}< 0.3$. The statistical errors are represented by vertical bars, the systematic errors by boxes around data points. The relative systematic uncertainties on the normalization are shown as boxes around unity near $p_{\mathrm{T}}=0$.
