Abbreviations: UACR urinary albumin to creatinine ratio, 24-h Uur 24 h urinary uric acid excretion, BMI body mass index, eGFR estimated glomerular filtration rate, SUA serum uric acid, CRP C-reactive protein, UpH urinary pH, TG triglycerides, UBCR urinary β₂ microglobulin-creatinine ratio, UV urinary volume, Ug urinary glucose

model 1 adjusted for sex, age and BMI; model 2 plus eGFR and SUA; model 3 plus CRP, UpH, TG, UBCR, UV and Ug. Standardized beta coefficients (St B) refer to how many standard deviations a dependent variable will change per standard deviation increase in the predictor variable
