^a For the adjusted difference.

^b Standardized difference was calculated as the adjusted group difference divided by the within-group SD of iCVH for each respective group or subgroup. This SD was unadjusted and unweighted. The unadjusted SD for the total program and comparison groups were 0.96 and 1.03, respectively (nearly identical to the weighted ones). Subgroup SDs were similar to these values.

^c The share of the group difference explained by educational attainment is calculated as the change in the group difference from the unmediated to mediated model divided by the unmediated group difference times 100.

^d Measured as the percentage of population at or below the federal poverty level, with 40% or greater indicating high and less than 40% indicating low.

^e High family risk is defined as the presence of 4 or more risk factors vs 0 to 3 factors, based on the American Heart Association iCVH.
