Top panel: \ynp{1}{S} and \ynp{n>1}{S}/\ynp{1}{S} in the \inelgz event class for all particles under study. Model predictions by \pem, \pecrr and \eplhc are shown as dotted, continuous, and dashed lines, respectively. Central panel: deviation between data and models in units of the total uncertainty. Bottom panel: deviation from independent production hypothesis for both data and models. Results for different particles are shifted in $x$ to improve visibility.
