The study included observational studies of patients who experienced OHCA and were successfully resuscitated using BCPR, following the predetermined criteria for inclusion and exclusion. The quality of the included studies was assessed using the Newcastle-Ottawa scale, with odds ratios (ORs) and 95% confidence intervals (95%CI) used as effect size measures. The data were statistically analyzed using Review Manager 5.4 software. <b>Results:</b> Fourteen observational studies were included in this study, involving 253,247 cases of OHCA.

Sepsis-related biomarkers are essential for diagnosis, treatment, and prognosis; however, their widespread application is limited by their insufficient sensitivity and specificity.
