Treatment contrasts for MI-IOP vs. MI-PC coded as MI-IOP=1; MI-PC=0. Contrasts for MI-PC vs. no further outreach coded as MI-PC=1; no further outreach= 0.

Models include binary indicators of Site (VA versus nonVA), Study (P01 versus P60), and a nominal indicator for study month.

Effect sizes are indicated by Odds Ratios (OR) for the dichotomous outcomes and BETA and Cohen’s d values for continuous outcomes. CI= confidence intervals
