The measured 13-to-7 TeV ratios of hadron \pt spectra are compared with model calculations: where $Y$ is the particle yield, the plotted double ratio is $(Y^{13\;\mathrm{TeV}}_{\mathrm{model}}/Y^{7\;\mathrm{TeV}}_{\mathrm{model}})/(Y^{13\;\mathrm{TeV}}_{\mathrm{measured}}/Y^{7\;\mathrm{TeV}}_{\mathrm{measured}})$. The measured \pt spectra at \sppt{7} are from Refs. . The total fractional uncertainties of the measured yield ratios are shown as shaded boxes
