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.
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
backgroundAvoidant/Restrictive Food Intake Disorder (ARFID) is an underdiagnosed eating disorder consisting of food avoidance that is not related to body image concerns. New evidence suggests that individuals identified as having ARFID experience elevated suicidal ideations. This association could be mediated by alexithymia, described as having difficulty in recognizing or verbalizing emotions. Therefore, this study aimed to determine whether alexithymia mediates the link between ARFID symptoms and suicidal ideation among Lebanese adults.
methodsBetween September and December 2024, a cross-sectional study was conducted using snowball sampling technique. 396 Lebanese adults (mean age = 26.26) took an online Arabic survey.
results40.7% of the participants had thoughts of suicide. Younger age, being unmarried, less physical activity, higher ARFID scores, and increased alexithymia were significantly associated with suicidal ideation. Alexithymia fully mediated the link between ARFID symptoms and suicidal ideation (indirect effect: Beta = 0.02; Boot SE = 0.01; Boot 95% CI 0.01, 0.04). There was a strong correlation between higher avoidant/restrictive food intake disorder and higher alexithymia. There was also a significant association between higher alexithymia and the presence of suicidal ideation. Finally, there was no association between avoidant/restrictive food intake disorder and suicidal ideation.
conclusionOur findings support alexithymia as a fundamental psychological process linking ARFID symptoms and suicidal ideation. Given the sociocultural stigma and limited mental health resources in Lebanon, clinicians should consider screening for alexithymia among individuals with eating disorders and suicidal thinking. Interventions that focus on emotions could therefore be used to reduce suicide risk in this vulnerable population.
