Significant p-values are indicated in bold. All models controlled for social network members’ age, sex, education, relationship status, employment status, self-rated health, trial participants’ program attendance, and baseline value of outcome of interest as fixed effects. Trial program sites and trial participants’ identification number were treated as random effects in all models.
