  • a Interpretation of the equation for ACR: ACR (mg/mmol) = 10(−0.051 × BW-sds)/10(−0.005 × residual adult weight)/10−0.002 if male. Without adjustment for residual weight and gender, the coefficient and 95% confidence interval (CI) for BW-sds to log ACR is nearly equal (−0.050, 95% CI: −0.091 to −0.010).
