Donor information from deceased donor kidney transplants to child recipients under the age of 10 at listing before and after the implementation of KAS. For categorical variables, number of yearly transplants in each category is reported with percentage of yearly lists in parentheses. For continuous variables, mean ± SD or median with [intra quartile range] are reported. Young pediatric recipients were significantly less likely to receive a kidney from pediatric donors (21% vs 32%, P < .001) and received organs from larger donors based on height, weight, and BMI.
Robust standard errors clustered by transplant center calculated using linear regression for continuous variables and multinomial logit for categorical variables. Incidence rate ratio exact test was used to compare the rate of transplant in the 2 periods. Significant results at the P < .05 level are bolded.
