Particle yield ratios $\Lambda/{\rm K}^{0}_{S} = (\Lambda+\overline{\Lambda})/2{\rm K}^{0}_{S}$ and ${\rm p}/{\pi} = ({\rm p}+\overline{\rm p})/({\pi}^{+}+{\pi}^{-}$) as a function of $\langle {\rm d}N_{\rm ch}/{\rm d}\eta \rangle$. The yield ratios are measured in the rapidity interval $\left|y\right| < 0.5$. The error bars show the statistical uncertainty, whereas the empty and dark-shaded boxes show the total systematic uncertainty and the contribution uncorrelated across multiplicity bins, respectively. The values are compared to calculations from MC models [30-32] in pp collisions at $\sqrts = 7$ TeV and to results obtained in p-Pb collisions at the LHC [10]. The indicated uncertainties all represent standard deviations.
