Psychometric validity and clinical utility of the GHQ-12 for screening psychological health in isolated, confined and unusual or extreme environments.

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
This study evaluated the psychometric validity and clinical utility of the 12-item General Health Questionnaire (GHQ-12) in isolated, confined and unusual or extreme (ICUE) work environments in South Africa. Two occupational health surveillance cohorts ( Contribution: This study provides the first large-scale evaluation of the GHQ-12 in ICUE occupational environments in southern Africa. By combining psychometric evaluation with a clinically oriented grey-zone approach, it offers evidence to support how brief mental health tools can be applied to high-risk workplaces such as offshore vessels, submarines and polar research stations.
