Multiple linear regression analysis for the association of UACR (independent variable) with Cur (dependent variable)

	Model 1		Model 2		Model 3
	St B	P	St B	P	St B	P
UACR, mg/mmol	−0.262	< 0.001	− 0.118	0.007	− 0.144	0.007
Age, y	−0.013	< 0.001	−0.175	0.003	−0.137	0.019
SUA,umol/L			−0.537	< 0.001	−0.541	< 0.001
TG, mmol/L					0.193	< 0.001
UV					0.162	0.002

Abbreviations: UACR urinary albumin to creatinine ratio, Cur uric acid clearance rate, 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
