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

objectiveThe Fukushima nuclear disaster in 2011 caused psychological distress among plant workers. A three-year follow-up study was conducted to understand the longitudinal relationship between workers' alcohol drinking for stress coping and mental health symptoms.

methodsThe present study analyzed 405 Fukushima Daiichi and Daini nuclear power plant workers, who responded to the open-ended questions about their own stress reduction efforts in 2012. Elements were extracted from the descriptions and categorized into 'coping by drinking alcohol' and 'adaptive stress coping'. Mental health symptoms were assessed annually from 2012 to 2014. The relationships between stress coping and mental health symptoms over time were analyzed using a mixed-effects logistic regression model.

resultsThirty-five workers drank alcohol for stress coping (12 drank alcohol only; 23 reported adaptive stress coping as well). The workers who drank alcohol only had significantly high Impact of the Event Scale-Revised (IES-R) (β = 9.61, p = 0.008), Athens Insomnia Scale (AIS) (β = 2.66, p = 0.008), and CAGE scores (β = 1.38, p < 0.001) in 2012. The significant effects on IES-R and CAGE persisted through 2014; however, the effect on AIS decreased over time (β = -1.16, p = 0.045). The workers who drank alcohol and implemented adaptive stress coping had significantly higher CAGE scores in 2012 (β = -0.08, p = 0.008), and the impact increased over time (β = 0.51, p = 0.003).

conclusionsIn the study population, drinking alcohol for stress coping was associated with higher subsequent problem drinking, as well as post-traumatic stress response and insomnia, especially in the absence of adaptive stress coping. Because these effects persist over years, professional education and guidance and continuous monitoring of coping content are considered necessary from the early post-disaster period.
