A meta-analysis was performed for 5 outcomes (hospital stay, admission to intensive care unit, SIRS, progression of pancreatitis, CRP) from the studies of Madaria E et al. [27], Lee A et al. [26], Karki B et al. [25], Wu B et al. [29], and Choosakul et al. [28]. This evidence concerns the gene CRP and pancreatitis.
