A) Lognormal cumulative distribution functions of annualized glomerular filtration rate (GFR) ratios based on random intercepts and random-slopes mixed models for 420 children with nonglomerular chronic kidney disease (black dashed curve) and 109 children with glomerular chronic kidney disease (black solid curve) from the Chronic Kidney Disease in Children Study, 2005–2010. Diagnosis-specific empirical cumulative distributions of annualized GFR ratios are shown as thin black step curves. B) Diagnosis-specific generalized gamma cumulative distribution functions superimposed on diagnosis-specific empirical cumulative distributions of annualized GFR ratios (shown as thin black step curves).
