Figure 2: Odds of Smoking Cessation From Random-Effects Meta-Analysis of Trials with Smokers Potentially Eligible for Lung Screening Based on 7-day Point Prevalence of Abstinence at 6-Months by Primary Intervention Type (n= 74 Trials)*.

Figure 2:

Forest plots display weighted odds ratios and 95% confidence intervals of included trials. Trial weights are generated from a random effects analysis. Squares around point estimates indicate study weight relative to the lowest weighted study for each meta-analysis. The vertical dashed line represents the pooled odds ratio with the diamond representing the 95% confidence interval.

* Some trials included more than one intervention of a differing generic type so that the sum of the sample of all intervention types is greater than the total number of trials included.
