1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo evaluate new strategies to enhance the promotion of smoking cessation in general practice.

designCluster randomised trial, 2x2 factorial design.

setting82 medical practices in Germany, including 94 general practitioners.

participants577 patients who smoked at least 10 cigarettes per day (irrespective of their intention to stop smoking) and were aged 36-75 years.

interventionsProvision of a 2-h physician group training in smoking cessation methods and direct physician payments for every participant not smoking 12 months after recruitment (TI, training+incentive); provision of the same training and direct participant reimbursements for pharmacy costs associated with nicotine replacement therapy or bupropion treatment (TM, training+medication).

main outcome measureSelf-reported smoking abstinence obtained at 12 months follow-up and validated by serum cotinine.

resultsIn intention-to-treat analysis, smoking abstinence at 12 months follow-up was 3% (2/74), 3% (5/144), 12% (17/140) and 15% (32/219) in the usual care, and interventions TI, TM and TI+TM, respectively. Applying a mixed logistic regression model, no effect was identified for intervention TI (odds ratio (OR) 1.26, 95% confidence interval (CI) 0.65 to 2.43), but intervention TM strongly increased the odds of cessation (OR 4.77, 95% CI 2.03 to 11.22).

conclusionProviding cost-free effective drugs to patients along with improved training opportunities for general practitioners could be an effective measure to achieve successful promotion of smoking cessation in general practice.
