Key Points Question Are kidney health outcomes different in children and adolescents compared with adults with focal segmental glomerulosclerosis (FSGS)? Findings This cohort study with 482 patients from 3 independent cohorts found no significant differences by age in the median time to kidney failure, 11.9 years, or to the composite outcome of time to kidney failure or 40% reduction in kidney function, 5.7 years, despite differences in clinical context and medical management. Meaning These findings suggest that the adverse outcomes of FSGS on kidney survival are severe and comparable across the lifespan.
