*
Normally distributed data reported as means (standard deviation) and evaluated using one‐way ANOVA;
**
Non‐parametric data reported as medians (interquartile range) and evaluated using Kruskal–Wallis test; stdev = standard deviation; IQR = interquartile range;
***
Days postpartum data represents n = 30 for BANKED, n = 28 for MOM, n = 30 for SCREENED, and n = 19 for SHARED due to missing data on parturition date.
