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

backgroundThe aim of this study was to explore perceptions of free will in the repetitive behaviors of patients with obsessive-compulsive disorder (OCD) and to explore their relation with core clinical characteristics.

methodsExperiences of free will were assessed with the Symptomatology And Perceived Free will rating scale (SAPF) in 295 subjects with a lifetime diagnosis of OCD. Patients' scores on the SAPF were subjected to an explorative principal axis factor analysis (PAF). Factor scores were regressed on five OCD symptom dimensions and on seven clinical variables: illness duration, severity of OCD, insight, anxiety and depression, suicidal ideation and quality of life.

resultsThe PAF revealed three factors: the perceived ability to control and change one's course of action when faced with an obsession or compulsion (the "alternative possibilities" factor); the experience of obsessions or compulsions as intentional (the "intentionality" factor); and the experience of being the source or owner of the obsessions or compulsions (the "ownership" factor). Lower scores on the "alternative possibilities" factor were associated with lower scores on the washing dimension (β = 0.237, p = 0.004) and higher scores on the precision dimension (β = - 0.190, p = 0.025) and independently associated with longer illness duration (β = - 0.134, p = 0.039), higher illness severity (β = - 0.298, p < 0.001) and lower quality of life (β = 0.172, p = 0.046). Lower scores on the "intentionality" factor were independently associated with lower quality of life (β = 0.233, p = 0.027). Higher scores on the "ownership" factor were associated with higher scores on the precision dimension (β = 0.207, p = 0.023) and independently associated with poorer insight (β = 0.170, p = 0.045).

conclusionsThe most notable finding of this study is that a diminished experience of free will in OCD is associated with core clinical characteristics: illness duration and severity, insight and quality of life.
