Table 3.

Logistic regression for the weighted odds of having made a quit attempt in October compared with other months, comparison of high budget and low budget Stoptober campaigns within Stoptober period (2012–2017). n = 26 611

	Odds ratio (95% confidence interval)^a	p-value	Bayes factor
October^b
Low	0.90 (0.59 to 1.39)	.643	0.45
High	1.35 (1.06 to 1.73)	.017	5.80
Stoptober budget × October^c
Low	Ref
High	1.50 (0.92 to 2.44)	.106	2.21

^aAdjusted for month of the year, month of the study, age, gender, social grade, cumulative tobacco control policy score, tax increases, mass media campaign expenditure.

^bOctober coded as 1 = October versus 0 = other months of the year, budget coded as high = 2012–2015 versus low = 2016–2017. Odds ratios (Ors) represent odds of quit attempt in October versus other months of the year, within high budget and low budget Stoptober campaigns.

^cOR represents difference in odds of quit attempt in October versus other months of the year, between high budget and low budget Stoptober campaigns.
