z-scores were age- and sex-specific; bolded mean z-scores indicate significant differences (P < 0.05) between those with birth abnormality compared to those without the indicated birth abnormality using generalized estimating equations to account for the statistical dependence incurred by repeated measures of each outcome on the same individual.
A total of 89 children with a glomerular CKD diagnosis contributed a total of 286 person-visits (9 [10%] contributed one visit, 11 [12%] contributed two visits, 31 [35%] contributed three visits, 29 [33%] contributed four visits, 8 [9%] contributed five visits, and 1 [1%] contributed six visits).
Growth hormone use was missing at 77 person-visits.
