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

backgroundThis study aimed to estimate the prevalence of chronotypes among male prisoners in China and to examine the relationship between chronotype, insomnia, and depressive symptoms in this population.

methodsA total of 1609 male inmates participated in this cross-sectional study by completing the Morning and Evening Questionnaire-5 (MEQ-5), Insomnia Severity Index (ISI), and Patient Health Questionnaire-9 (PHQ-9). Age, time served, insomnia, and depressive symptoms were compared across chronotypes. Binary logistic stepwise regression was used to analyze factors influencing depression. Additionally, a simple mediation model incorporating MEQ-5, ISI, and PHQ-9 was analyzed, with age controlled as a covariate.

resultsThe prevalence of morning type (MT), neutral type (NT), and evening type (ET) was 47.2%, 46.7%, and 6.1%, respectively. Being an ET was significantly associated with younger age and increased symptoms of insomnia and depression (P < 0.05). The relative risk of depression was 2.970-fold higher (95% CI, 1.724 to 5.116; P < 0.001) for ET compared to MT. Mediation analysis revealed that insomnia partially mediated the relationship between chronotype and depression, while the direct effect of chronotype on depression was also significant (accounting for 50.51% of the total effect).

conclusionsThe prevalence of ET is relatively low among male prisoners. Resetting ET tendencies may reduce depressive symptoms in this population.
