Impact of the intensified follow-up procedure of patients lost to 6-month follow-up after an intensive smoking and nicotine cessation intervention in practice: a cohort study.

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.
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
backgroundPost-intervention follow-up is challenging in research and practice. In tobacco reports, patients with missing follow-up were considered smokers. Based on patient and staff preferences, an add-on intensified follow-up procedure after intensive tobacco and nicotine cessation interventions was developed. This study examined the impact of the new procedure on patients lost to follow-up and compared their cessation status with that of those who completed routine follow-up.
methodsBetween January and February 2023, 2114 patients participated in the Danish STOPbase for Tobacco and Nicotine after providing informed consent. Overall, 1529 (72%) patients completed routine 6-month follow-up interviews, 136 (6%) patients rejected follow-up participation and 449 (21%) patients were lost to follow-up. Of the 449 patients, 225 patients were randomly selected to undergo the new follow-up procedure with repeated information, up to four extra calls, texts and voice messages from known telephone numbers.
resultsUsing the new procedure, 143/225 (64%; 95% CI: 61% to 67%) patients completed the follow-up, with a continuous quit rate of 54/225 (24%; 21% to 27%). The lost to follow-up group had a significantly lower continuous cessation rate than the group that completed the routine follow-up: 54/143 (38%; 34% to 42%) and 703/1529 (46%; 45% to 47%), respectively, (p<0.01).
conclusionAlmost two-thirds of the patients lost to 6-month follow-up completed the intensified follow-up procedure and had substantially lower cessation rates than those completing routine follow-up. However, this finding is clinically relevant, as a high follow-up rate impacts the reliability of outcomes, with loss to follow-up reported on continuous use.
