Note: ITT, intent to treat; analyses based on the smokers of all randomized support persons (n = 704). PP, Per protocol; analyses based on the smokers of support persons completing the 7-month follow-up.
Chi-square test.
From logistic regression: one call group versus control, OR = 2.51, 95% CI: 1.33-4.74, P = 0.005.
From logistic regression: three call group versus control, OR = 2.55, 95% CI: 1.35–4.82, P = 0.004.
The number in each study group was one call group = 166, three call group = 165, and control group = 169.
From logistic regression: one call group versus control, OR = 2.23, 95% CI: 1.10–4.51, P = 0.026.
From logistic regression: three call group versus control, OR = 2.78, 95% CI: 1.40–5.52, P = 0.004.
Of smokers who enrolled in the quitline; calculated from date of support person’s enrollment.
