Meta-analyses and systematic reviews (MSR) have been conceived as tools to summarize evidence on a specific health question. However, in the last years, an exaggerated number of MSRs published by scientific journals has been observed, i.e. 286 MSRs in the field of Resuscitation Science over the last 3 years, i.e. approximately 95 per year. Thus, doubts on the real scientific need of such a high number of MSRs may arise, potentially being only a way to rapidly improve authors' citation index and fame and sometimes the journals' impact factor.

Bystander cardiopulmonary resuscitation (CPR) is a critical factor in improving out-of-hospital cardiac arrest (OHCA) survival. The aim of this study was to investigate the interaction effect of bystander sex and patient sex on the provision of bystander CPR. ⋯ Female bystanders have a lower likelihood of providing bystander CPR than male bystanders. Additionally, an interaction was observed between bystander sex and patient sex in the providing bystander CPR, with the association being more pronounced in male OHCA patients.
