Fit of the antiparticle-to-particle ratios of charged pions, protons, hypertriton ($^3_{\Lambda}\mathrm{H}$), $^3\mathrm{He}$, obtained in the 0-5% (left, orange), 5-10% (center, blue), and 30-50% (green, right) centrality intervals using the relation obtained from the Statistical Hadronisation Model (SHM). The vertical bars represent the sum in quadrature of the statistical and centrality-uncorrelated systematic uncertainties on each measured ratio. The fit values obtained for each particle species are shown as horizontal black lines for each centrality interval. The $\chi^2/\mathrm{NDF}$ is reported for each centrality class. In the bottom panels, the difference between data and fit normalised to the data uncertainty is reported.
