1DKA severity was defined using the first venous pH obtained: mild (pH > 7.2 to <7.25), moderate (pH > 7.1 to <7.2), and severe (pH < 7.1). For children with no pH documented prior to treatment, serum bicarbonate concentration was used: mild (bicarbonate ≥ 10), moderate (bicarbonate 5 to <10), and severe (bicarbonate < 5). DKA severity was unknown for one newly diagnosed child. 2Mean (25th and 75% percentile) and p-values from Wilcoxon rank sum tests are presented for age; n (%) and p-values from Fisher’s exact tests are presented for all other characteristics. 3Maternal parental education and household income information were not collected for the retrospective cohort; number nonmissing and analyzed were (mild/moderate/severe DKA): (299/163/121) newly diagnosed and (234/242/141) previously diagnosed for maternal parental education, and (298/163/118) newly diagnosed and (238/253/152) previously diagnosed for household income.
