\pt-integrated yields in pp collisions at different center-of-mass energies and midrapidity as a function of the event multiplicity for \kzero and \lmb (top panels), \Xiboth and \Omboth (bottom panels). \five results are shown as black dots, \seven results~ as green squares and \thirteen results~ as red diamonds. Statistical uncertainties are represented as error bars and systematic uncertainties as boxes whose width represent the systematic error on the multiplicity determination. Linear combined fits are shown as dashed lines, while the quadratic fit to the \Omboth progression is shown as a dotted line.
