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

Obsessive-compulsive disorder is frequently accompanied by sleep disturbances, particularly insomnia and circadian dysregulation. These conditions are increasingly recognised not only as comorbidities but also as factors potentially influencing the severity and course of obsessive-compulsive symptoms. This systematic review synthesises findings from 28 studies investigating the association between obsessive-compulsive disorder, insomnia and circadian alterations across different age groups. Insomnia was found to be highly prevalent among individuals with obsessive-compulsive disorder and associated with greater symptom severity, especially regarding intrusive thoughts and cognitive-affective dysregulation. Circadian disruptions, such as delayed sleep phase, evening chronotype, and atypical hormonal rhythms, were frequently observed and related to emotional instability and clinical variability. These results underscore the importance of systematically assessing and addressing sleep-related disturbances in patients with obsessive-compulsive disorder. Integrating sleep and circadian-focused strategies into clinical care may improve treatment outcomes and provide insight into underlying neurobiological mechanisms.
