Effects of alcohol misuse on the evolution of anxiety during the COVID-19 pandemic in France: results from CONFINS cohort.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesto describe the evolution of anxiety during the COVID-19 pandemic in France and to assess whether it differed according to pre-existing alcohol misuse.
designA prospective longitudinal study.
settingA French online cohort: CONFINS. Data has been collected since the first lockdown in April-May 2020 until January 2022.
participants1868 participants being at least 18 years of age and who had been confined in France by government measures. PRIMARY OUTCOME MEASURE: The primary outcome was anxiety, measured through
resultsOf the 1868 included participants, 729 responded to at least one follow-up questionnaire (median follow-up time: 46 weeks). We identified 58% as having pre-existing alcohol misuse. Alcohol misuse was significantly associated with an increased GAD-7 score starting at the second lockdown in women (β=0.30; p=0.014) and in participants having a high perceived loneliness (β=0.59; p=0.011).
conclusionsPre-existing alcohol misuse appeared to be a risk factor for anxiety during the COVID-19 pandemic, particularly for women and those with high perceived loneliness. Mental health support should be proposed to these vulnerable groups in the event of a future health crisis.
