According to Spearman's correlation analysis, ALB was negatively correlated with the occurrence of uremia (P < 0.05), r = −0.320, NLR and PCT were positively correlated with the occurrence of uremia (P < 0.05), r = 0.313, respectively, and 0.417; in addition, Pearson's correlation analysis showed that ALB was negatively correlated with NLR and PCT in the two groups (P < 0.05, r = −0.507, −0.605 in the control group, respectively, and r were −0.452 and −0.412 in the observation group). Here, ALB is linked to uremia.
