ResultadoTotal-slope difference +0.3 mL/min/1.73m²/yr (95% CI −1.7 to 2.4; primary eGFR-slope endpoint missed); FSGS partial remission 42.0% vs 26.0% (p=0.009).

Discusión y crítica
A clean example of proteinuria reduction without an eGFR-slope benefit; no FSGS approval, unlike for IgA nephropathy.
