Model adjusted for APOL1 genotype, log-baseline UP:C, baseline eGFR, and treatment arm. Non-significant covariates removed during model selection include age, sex, race, systolic blood pressure index, and reduction in systolic blood pressure index (baseline - week 26). “Persistent proteinuria” refers to 0% reduction in UP:C. Multiple imputation by fully conditional specification was used to handle missing data. Observation “time” for eGFR outcome measurements=week 26 to last follow-up (maximum of month 54 from baseline).
Abbreviations: 95% CI, 95% confidence interval; APOL1, Apolipoprotein L1; eGFR, estimated glomerular filtration rate; UP:C, urine protein: creatinine ratio.
