(a) The survival analysis showing time to progression of chronic kidney disease (CKD) in children with glomerular disease in comparison to those with nonglomerular disease. Children with glomerular disease had a higher risk of progression when compared to those with nonglomerular disease (hazard ratio 2.59, 95% confidence interval 1.07, 6.27, P = 0.034). (b) Survival analysis comparing time to progression of CKD among children with proteinuria (urine protein-to-creatinine ratio [UPCr] > 2) and those without proteinuria. UPCr > 2 at baseline was associated with the risk of progression of CKD (hazard ratio 3.1, 95% confidence interval 1.33, 7.23, P = 0.009).
