Simultaneous vs. sequential treatment for smoking and weight management in tobacco quitlines: 6 and 12 month outcomes from a randomized trial

Table 1 30-day point prevalent abstinence at 6 months and 12 months by treatment group

	Control N = 840	Sequential N = 849	Simultaneous N = 839	Weight management treatment vs control: Wald’s X2; p-value
6-month outcomes
% abstinent (Multiply Imputed)	44.9	48.3	40.3	2.94; p = 0.08^a
% abstinent (Missing = Smoking)	24.4	23.8	19.2	7.84; p = 0.02^b
12-month outcomes
% abstinent (Multiply Imputed)	46.0	46.3	40.7	1.83, p = 0.16^c
% abstinent (Missing = Smoking)	28.2	26.9	24.1	3.89, p = 0.14

^aThere was a statistically significant difference between the simultaneous and control groups (p = 0.036) and between simultaneous and sequential (p = 0.032).
^bThere was a statistically significant difference between the simultaneous and sequential groups (p = 0.024) and between the simultaneous and control groups (p = 0.01).
^cSimultaneous group was significantly different from controls (p = 0.039)
