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

Objective: Obsessive-compulsive disorder (OCD) is a psychiatric disorder characterized by the presence of obsessions and/or compulsions that cause significant distress and functional impairment. Despite extensive research, its etiopathogenesis remains incompletely understood. Recent evidence suggests that dysfunction in tight junctions may contribute to the pathophysiology of various psychiatric disorders. Tight junction proteins play a crucial role in maintaining blood-brain barrier integrity and regulating neuronal signaling. This study aims to investigate the involvement of tight junction proteins in the etiopathogenesis of OCD, providing new insights into their potential role in the disorder's neurobiological mechanisms. Methods: A total of 41 medication-free children and adolescents with OCD and 41 healthy controls were included in this study. The participants filled out self-report scales to determine various psychological variables. Blood samples were collected from all participants to measure the levels of claudin-5, claudin-12, occludin, angulin-1, and tricellulin. Results: The levels of claudin-5, claudin-12, occludin, and tricellulin were significantly higher in the OCD group compared to the control group. However, there was no significant difference in angulin-1 levels between the groups. Conclusion: Our findings indicate that claudin-5, claudin-12, occludin, and tricellulin levels differ between individuals with OCD and healthy controls. These results suggest that tight junction proteins may contribute to the etiopathogenesis of OCD. Further research is needed to better understand the relationship between OCD and tight junction proteins.
