  • a HR, hazard ratio; Rate per 1000, number of ESRD end points per 1000 patient-years of follow-up. To convert urinary albumin in mg/g to mg/mmol, multiply by 0.113; serum creatinine in mg/dl to μmol/L, multiply by 88.4; hemoglobin in g/dl to g/L, multiply by 10; and serum albumin in mg/dl to g/L, multiply by 10.
