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

<p>Introduction: Exposure to trauma has been theorized to contribute to the onset and exacerbation of obsessive-compulsive disorder (OCD), yet direct empirical evidence remains limited. This study examined whether individuals directly affected by the trauma of October 7th, 2023, in Israel exhibited higher rates of new-onset or worsening OCD symptoms compared to controls who were not directly affected.

methodsA total of 132 adults participated, including 66 survivors from the Gaza envelope who experienced direct exposure to the attacks and 66 matched controls from other areas of Israel who were not directly affected. Data on OCD and post-traumatic stress disorder (PTSD) symptoms were collected approximately 4-6 months after the events.

resultsThe data revealed significantly higher OCD symptoms in the directly affected group and PTSD symptom severity partially mediated the relationship between trauma exposure and increased OCD symptoms. Notably, 39% of individuals in the directly affected group met a priori criteria for probable OCD, 24% reported new-onset symptoms after October 7th, and most others reported worsening of existing symptoms.

conclusionThese findings provide the first direct evidence that acute trauma can trigger new-onset and worsening OCD symptoms. Consistent with the diathesis-stress model, the results underscore the role of environmental stressors in OCD etiology and highlight the need for screening for OCD in trauma-exposed populations. </p>.
