Statistical analysis between interleukin 37 (IL-37) secretion levels and biochemical indicators. A, Differences in arterial lactic acid, lactate, and lactate dehydrogenase (LDH) levels between the low– and high–IL-37 groups. B, Myoglobin, creatine kinase (CK), and D-dimer levels in the 2 groups. C, Statistical analyses of total bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels. D, A significant difference in erythrocyte sedimentation rate (ESR) was detected between the 2 groups. Creatinine and albumin levels were also analyzed. Dotted lines represent normal ranges of indicators. Data were analyzed using unpaired 2-tailed Mann-Whitney U tests. P values are represented as *P < .05,**P < .01, ***P < .001,****P < .0001.
