4.1 | Limitations
Our study had some limitations. The most important limitation of our study was small sample size and its retrospective design. Second, other inflammatory markers such as cytokines were not investigated in this study. Third, long term outcomes were not evaluated. It could be interesting to determine the effect of CAR on long term outcomes. Further prospective studies with larger participant is needed to better elucidate the prognostic role of CAR in patients with OHCA.
