Vegetarian diet and orthorexia nervosa: a review of the literature.
Review in Eating and weight disorders : EWD, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 papers, 2 of them syntheses that pooled 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.
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 number of individuals following a vegetarian diet has increased in the last 50 years. Although the causal connection between orthorexic behaviors and vegetarianism remains widely assumed, evidence in support of this assumption has been largely inconsistent.
objectiveThe purpose of the study was to conduct a review of the relationship between vegetarian diet and orthorexic eating behavior and to give future directions in this area.
methodsA search of the literature within PubMed/Medline was conducted. The search terms were "orthorexia", "orthorexic", "orthorexia and vegetarian", "orthorexia and vegan" and "orthorexia and vegetarianism". Out of 117 journal articles, 14 met the predefined inclusion criteria and were analyzed.
resultsThe results demonstrated that following a vegetarian diet was found to be related to orthorexic eating behaviors (in 11 out of 14 studies).
conclusionFurther longitudinal research is needed to investigate whether following a vegetarian diet serves as a risk factor in the development of orthorexia nervosa. LEVEL OF EVIDENCE: Level V, narrative review.
