Figure 5. The relationship between the expression of miR-21 and NLR and the survival of patients at 30 days. A. The survival rate of patients was found to be significantly lower in the miR-21 high-expression group than in the low-expression group, and there was a significant difference between the high-expression group and the low-expression group. B. The survival rate of the NLR high-expression group was significantly lower than that of the low-expression group. There was a significant difference in 30-day survival.
