Table 2.

Smoking cessation outcomes between intervention (n = 45) and control condition (n = 38).

Smoking Cessation Outcomes	Telephone Counseling % (n)	Self-Help Brochure % (n)	OR (95% CI) *
Primary outcome
7-day PPA at 3-month FU	53.3 (24)	13.2 (5)	7.54 (2.49–22.84)
Secondary outcomes
24 h PPA at 3-month FU	60.0 (27)	18.4 (7)	6.64 (2.41–18.31)
14-day PPA at 4-week after the designated quit date	55.6 (25)	13.2 (5)	8.23 (2.72–25.02)

Notes. Intention-to-treat analyses were carried out. In accordance with the Russell Standard criteria, parents who did not complete the follow-up assessment were considered “smokers”. CI = confidence interval. PPA = point prevalence abstinence. FU = follow-up * Because none of the baseline variables shown in Table 1 were significantly correlated with the primary outcome, no adjusted ORs were calculated.
