Exhibit 2. Average Absolute Standardized Mean Difference of Baseline Covariates in Weighted and Unweighted Samples.

Exhibit 2.

Note: The absolute standardized bias difference for each baseline covariate was calculated separately using weights for each 3-month time period. This figure reports the average of this value across all 13 time periods. The absolute standardized bias difference is defined as the absolute difference in means between the BHH-enrolled and non-BHH-enrolled groups standardized by the standard deviation of the entire sample. Vertical line at 20%, a suggested threshold for good balance given in Griffin et al.
