The hadron cascade model is an essential part of Monte Carlo neutrino event generators that governs final-state interactions of knocked-out nucleons and produced pions. It is shown that such a model enriched with physically motivated modifications of nucleon-nucleon cross sections and incorporation of nuclear correlation effects is able to reproduce experimental nuclear transparency data. The uncertainty of nucleon final-state interaction effects is estimated and applied to recent neutrino-nucleus cross section measurements that include an outgoing proton in the experimental signal. Conclusions are drawn on a perspective of identification of events that originate from the two-body current mechanism.
