Insomnia Severity is Associated with Morning Cortisol and Psychological Health.

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
Studies suggest associations between cortisol and sleep, and cortisol shows a profound diurnal rhythm. The evidence about the relationship between chronic insomnia and cortisol is mixed. Chronic insomnia is associated with the risk of mental health disorders. The aim of this study was to evaluate the association of insomnia severity and objective sleep pattern with morning cortisol level and psychological health. The instruments used were the Insomnia Severity Index (ISI), polysomnography, Beck Depression Inventory (BDI), and Profile of Mood States (POMS). Serum cortisol was analyzed by chemiluminescence. The data revealed significant positive correlations of ISI with morning cortisol level (r = 0.37,
