P value <0.05 indicated statistical significance. * indicated statistical significance. aFisher’s exact test was used for the nominal variable. Wilcoxon test was used for the ordinal variable, whose statistics is W. Student’s t test was used for the continuous variable with abnormal distribution, whose statistics is t. bIt is same to Table 1. SD, standard deviation; WBC, white blood cell; NE, neutrophil; PCT, procalcitonin; hs-CRP, high-sensitivity C-reactive protein.
