Values are means (95% CIs); = 30, 23, and 21 in the parent mentor group and 30, 25, and 20 in the community health worker group at baseline and at 6 and 12 months, respectively. Linear mixed-model analysis on the entire study population; values are for the individual effects of group and time as well as their interaction. 0–6-month mean difference significance at a value < 0.05; 6–12-month mean difference significance at a value < 0.05; 0–12-month mean difference significance at a value < 0.05.
