$\pT$-dependent $\Lambda$/${\rm K_S^0}$ ratio for 0$-$10% (left panel), 10$-$40% (middle panel) and 40$-$100% (right panel) event multiplicity classes. For each case, the results of JE particles (red inverted-triangle) are compared with that of inclusive (black closed circles) and UE (blue open circles) particles. The statistical uncertainties are represented by the vertical error bars and the systematic uncertainties by the boxes.
