The chi-square test and independent t test were used to compare the statin and non-statin groups, as appropriate. Kaplan–Meier analysis was used to draw the plot of the cumulative incidence of sepsis between statin group and non-statin group. A log-rank test was used to estimate the significance. A Cox proportional hazard model was used to estimate the hazard ratios of sepsis between the two groups. The analytical statistical software used was SPSS V.18.0 (SPSS, Chicago, IL, USA). Significance was defined as p < 0.05.
