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

Background: Trichotillomania (TTM) is a disorder within Obsessive-Compulsive and Related Disorders, involving repetitive hair-pulling leading to hair loss and functional impairment. It remains under-investigated in the Middle East. The Trichotillomania Dimensional Scale (TTM-D) has not been validated in Arabic-speaking populations. Methods: Arabic-speaking participants from Saudi Arabia, Egypt, Lebanon, Palestine, and Jordan were recruited online via snowball sampling (December 2024 and January 2025). The TTM-D was translated using forward-backward translation and expert panel review. Results: A total of 1494 participants from five Arab countries completed the survey. The structure of the TTM-D showed mixed model fit (CFI = 0.957, TLI = 0.914, RMSEA = 0.139, SRMR = 0.044), with excellent internal consistency ( Conclusion: The Arabic TTM-D demonstrated strong psychometric properties. These results support it as a culturally sensitive and reliable tool for assessing TTM in Arab populations. Further validation is needed to enhance its diagnostic utility and establish clinical cut-off scores.
