a
P values refer to comparisons between the intervention group and control group. Determined by using Pearson’s Chi-square test for categorical variables, t-test for normally distributed continuous variables, and nonparametric equality-of-medians test for non-normally distributed continuous variables.
b
Distance was the shortest driving distance from the home to the study hospital.
