Statistically significant results are presented in bold font.
b
Results for the following CCS chapters were not shown due to fewer than 10 total hospitalizations in the GCA cases: diseases of the blood and blood forming organs; complications of pregnancy (females only); congenital anomalies; certain conditions originating in the perinatal period; and residual codes/unclassified.
