Heterogeneous cohort. Although the size of the two study groups is different, both groups have a similar range in time from diagnosis until ESKD. The time from diagnosis to ESKD varied greatly (range: 0–20 years) in both study groups, indicating a heterogeneous cohort, although there were few significant differences between the two groups at baseline (A). For instance, the eGFR at diagnosis was similar in both study groups, both among patients who progressed to ESKD within 10 years (p = 0.59) and those who took more than 10 years (p = 0.45) after diagnostic biopsy. Asterisks indicate the mean eGFR at diagnosis for each group (B). CS = Corticosteroids. ESKD = end-stage kidney disease. eGFR = estimated glomerular filtration rate
