Smoking status and the onset of suicidal ideation among adults in Japan during the COVID-19 pandemic.
Article in Annals of general psychiatry, 2025. 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
purposeAs previous research has linked smoking to suicidal behavior, it is possible that smoking may have played a role in suicidality during the COVID-19 pandemic. However, relatively little research has examined this association. To address this gap, the present study examined the relationship between smoking status and the onset of suicidal ideation in Japan during the pandemic.
methodsData were analyzed from 3,164 adults from the Japanese general population who participated in an online survey in early 2023. Information was collected on smoking status and incident suicidal ideation during the COVID-19 pandemic. Logistic regression was conducted to examine associations.
resultsIn a fully adjusted analysis, current smoking was associated with significantly higher odds of the onset of suicidal ideation in the total sample (OR: 2.31, 95%CI: 1.37, 3.90). In a sex-stratified analysis, both former (OR: 4.49, 95%CI: 1.75, 11.50) and current smoking (OR: 6.12, 95%CI: 2.67, 14.01) were associated with the onset of suicidal ideation in men, whereas no such association was observed in women.
conclusionSmoking was associated with the onset of suicidal ideation among adults in Japan during the COVID-19 pandemic, with the association observed in men but not women.
