To further explore factors influencing urolithiasis, we performed a multivariate analysis using urolithiasis as the dependent variable and the factors with P < .1 from the above results (sex, ethnicity, MetS, indirect bilirubin, total protein, albumin, urea nitrogen, creatinine, uric acid, neutrophil count, and TyG index) as independent variables in binary logistic regression (Table 6) analysis. This evidence concerns the gene ALB and metabolic syndrome.
