  1. Adjusted covariates: Model 0: univariate analysis; Model 1: age and BMI; Model 2: model 1 variables plus race, education and marital status; Model 3: model 2 variables plus hypertension and diabetes mellitus; Model 4: model 3 variables plus smoking status, physical activity status, blood urea nitrogen, creatinine and uric acid

Abbreviations: PSM Propensity score matching, SUI Stress urinary incontinence, BMI Body mass index, CI Confidence interval, aOR Adjusted odds ratio, PSM Propensity score matching, Q1-Q4, Quartile1-Quartile4: The total GS levels of the quartiles in the study population were: 15.9–47.7 kg (Q1), 47.8–55.4 kg (Q2), 55.5–63.1 kg (Q3), and 63.2–104.4 kg (Q4). The total rGS levels of the quartiles in the study population were: 0.414–1.552 kg (Q1), 1.552–1.933 kg (Q2), 1.935–2.349 kg (Q3), and 2.352–4.041 kg (Q4)
