Mean (left) and standard deviation (right) of the charged-particle transverse momentum spectra as a function of the charged-particle multiplicity for pp, p$-$Pb, and Pb$-$Pb collisions at a centre-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}}$ = 5.02 TeV. Statistical and systematic uncertainties are shown as bars and semi-transparent bands, respectively.
