Comparison of the ELISA results. (A) The S/CO value of the mild group was significantly higher than that of the severe/critical group (P = 0.00049). (B) There was no difference between two subgroups (P > 0.05). Values above the symbols denote mean concentration. *P < 0.05, **P < 0.01, ***P < 0.001, and ns = no significance.
