The \pt-integrated particle yield ratios \CKSshort/K, \NKSshort/K and $\phi$/K measured at midrapidity ($|y| <$ 0.5) in pp and Pb$-$Pb collisions at \snn $=$ 5.02 TeV as a function of $\langle $d$N_{\mathrm{ch}}/$d$\eta \rangle^{1/3}_{|\eta|<0.5}$. For Pb$-$Pb collisions, \NKSshort/K and $\phi$/K data points are taken from Ref.~ and for pp collisions \CKSshort/K is taken from Ref.~. The results of the Gamma canonical statistical model calculation~ for \NKSshort/K, in addition to predictions from the HRG-PCE model~, as well as MUSIC with and without afterburner~ are shown. Statistical uncertainties are shown by bars, total systematic uncertainties by open boxes, and the multiplicity-uncorrelated systematic uncertainty by the shaded boxes. The two highest multiplicity data points for \NKSshort\xspace and $\phi$ mesons are slightly shifted for visibility.
