Integrated \kaon/\pion (top) and \pr/\pion (bottom) yield ratios as a function of charged-particle multiplicity density measured in pp, p--Pb, and Pb--Pb collisions at different center-of-mass energies. Empty (shaded) boxes represent total (multiplicity uncorrelated) systematic uncertainties. Black lines represent predictions from different MC generators for pp collisions at \cme{13}.
