Ratios of the KNO-scaled multiplicity distributions at various centre-of-mass energies per nucleon pair relative to $\sqrt{s}$ = 13 TeV for pp collisions (top panel) and relative to $\sqrt{s_{\rm NN}}$ = 8.16 TeV and $\sqrt{s_{\rm NN}}$ = 5.02 TeV for p-Pb and Pb-Pb collisions, respectively (left and right bottom panels). Statistical and systematic uncertainties are shown as bars and semi-transparent bands, respectively.
