Subject counts across self-reported race and ethnicities are included. Group average values for age, body mass index and gestational age are provided, and 95% confidence interval is included within parenthesis. For the two CS groups, aggregated counts are included for different indications for CS. It is to be noted that the sum of these counts exceeds total number of subjects in the group as multiple indications were recorded for each subject when applicable.
+p-value corresponds to Fisher’s Exact Test for counts.
++p-values correspond to one-way ANOVA test across the three delivery modes.
