^aTwo sample t test for average women/month and Pearson Chi-square for categorical variables; comparisons do not include county 10

^bWeighted averages were computed by summing the number of women served in a particular county and dividing that total by the number of months of program implementation in that county; monthly averages for all hub-led counties were summed and divided by 24 months (the study period); similarly, monthly averages for all spoke-led counties (without county 10) were summed and divided by 24 months

^cMultiracial, other, and unknown races not shown for each group: 1.8, 2.3, and 4.1 %, respectively
