Associations between dietary consumption and sleep quality in young Japanese males.

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
purposePoor sleep quality has been reported to be a risk factor for cardiovascular disease, diabetes, and metabolic syndrome, as well as mental disorders including depression and anxiety. However, few studies have investigated the association between sleep quality and diet in young males. We aimed to assess this association, adjusting for psychological factors.
methodsIn this study, a total of 124 male Japanese students were analyzed. Sleep quality, diet, and psychological symptoms were assessed using self-reported questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), brief-type self-administered diet history questionnaire (BDHQ), 12-item General Health Questionnaire (GHQ12), and State-Trait Anxiety Inventory (STAI) A-Trait scale.
resultsAmong participants, 40% exhibited a PSQI total score ≥ 6, indicating poor sleep quality. Poor sleep quality was associated with poor mental health status and higher levels of anxiety. After adjusting for covariates including these psychological factors, poor sleep quality was significantly associated with low intakes of fat, beta-carotene, retinol, alpha-tocopherol, vitamin K, vitamin B
conclusionsOur findings demonstrated that sleep quality among young Japanese males was associated with specific dietary features, independently of psychological status, which may help to elucidate the mechanisms underlying the link between sleep and sleep-related diseases.
