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 a smoking cessation intervention that can be routinely delivered to smokers admitted with cardiac problems.

designRandomised controlled trial of usual care compared with intervention delivered on hospital wards by cardiac rehabilitation nurses.

settingInpatient wards in 17 hospitals in England.

participants540 smokers admitted to hospital after myocardial infarction or for cardiac bypass surgery who expressed interest in stopping smoking.

interventionBrief verbal advice and standard booklet (usual care). Intervention lasting 20-30 minutes including carbon monoxide reading, special booklet, quiz, contact with other people giving up, declaration of commitment to give up, sticker in patient's notes (intervention group).

main outcome measuresContinuous abstinence at six weeks and 12 months determined by self report and by biochemical validation at these end points. Feasibility of the intervention and delivery of its components.

resultsAfter six weeks 151 (59%) and 159 (60%) patients remained abstinent in the control and intervention group, respectively (P=0.84). After 12 months the figures were 102 (41%) and 94 (37%) (P=0.40). Recruitment was slow, and delivery of the intervention was inconsistent, raising concerns about the feasibility of the intervention within routine care. Patients who received the declaration of commitment component were almost twice as likely to remain abstinent than those who did not receive it (P<0.01). Low dependence on tobacco and high motivation to give up were the main independent predictors of positive outcome. Patients who had had bypass surgery were over twice as likely to return to smoking as patients who had had a myocardial infarction.

conclusionsSingle session interventions delivered within routine care may have insufficient power to influence highly dependent smokers.
