Top panels: The transverse momentum spectra of ${\rm K^{*0}}$ for five rapidity intervals within $-$1.2 $< y < $ 0.3 and for two multiplicity classes (0$-$10%, 40$-$100%) in p$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. The data for different rapidity intervals are scaled for better visibility. Bottom panels: The ratios of the $p_{\rm T}$ spectra in various rapidity intervals to that in the interval 0 $< y < $ 0.3 for a given multiplicity class. The statistical and systematic uncertainties are shown as bars and boxes around the data points, respectively.
