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

	Model 1		Model 2		Model 3
	St B	P	St B	P	St B	P
UACR, mg/mmol	0.203	0.003	0.118	0.051	0.016	0.759
eGFR, ml/min/1.73m2			−0.659	< 0.001	−0.386	< 0.001
SUA,umol/L			−0.322	< 0.001	−0.253	< 0.001
UBCR, mg/mmol					0.518	< 0.001
CRP, mg/L					0.154	0.004

Abbreviations: UACR urinary albumin to creatinine ratio, FEur fractional excretion of uric acid, 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
