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

aimsTo test whether the Stop-tabac smartphone application (app) increased smoking cessation rates.

designA two-arm, parallel-group, individually randomized, double-blind, controlled trial. SETTING AND

participantsA total of 5293 daily smokers (Stop-tabac = 2639, control = 2654) enrolled on app stores and on the internet in 2019-20, who lived in France or Switzerland. INTERVENTION AND COMPARATOR: The Stop-tabac application includes immediate feedback during episodes of craving and withdrawal; individually tailored counseling messages with notifications sent during 6 months; a discussion forum; fact sheets; modules on nicotine replacement therapy and e-cigarettes; and calculators of cigarettes not smoked, money saved and days of life gained since quitting. The control application included five brief pages and calculators as above. MEASUREMENTS: Primary outcome: self-reported smoking cessation after 6 months (no puff of tobacco in the past 4 weeks), with non-responders counted as smokers. SECONDARY OUTCOME: self-reported use of nicotine medications.

findingsParticipants were aged 36 years on average; 66% were women who smoked 15 cigarettes/day, and 64% screened positive for depression. Stop-tabac participants used the app over a longer period than control participants (23 versus 11 days, P < 0.001). Smoking cessation rates after 6 months were 9.9% in the Stop-tabac group versus 10.3% in the control group (odds ratio = 0.96, 95% confidence interval = 0.80-1.45, P = 0.63). Rates of use of nicotine medications after entry in the study were 38 versus 30% after 6 months (χ

conclusionsIn smokers enrolled on the app stores and the internet, allocation to the Stop-tabac smoking cessation app did not increase smoking cessation rates, but increased rates of use of nicotine medications.
