\avpt 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 reported as error bars, systematic uncertainties as boxes whose width represent the systematic error on the multiplicity determination.
