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

objectiveTo test the efficacy of a dissonance-based (DB) intervention in targeting risk factors for eating disorders (EDs) and predisposing factors for muscle dysmorphia (MD) symptoms in body-dissatisfied Brazilian men over 1 year of follow-up and evaluate whether reductions in body-ideal internalization would mediate the intervention's impact on ED and MD symptoms.

methodsParticipants were randomized to a two-session DB intervention (n=89) or assessment-only control (AOC) (n=91), and completed validated measures assessing body-ideal internalization, body dissatisfaction, ED, and MD symptoms at baseline, post-intervention, 1-month, 6-month, and 1-year follow-ups.

resultsThe DB condition showed significantly greater reductions in MD symptoms and body dissatisfaction compared with the AOC group over a 1-year follow-up, while significant differences were not observed for body-ideal internalization and ED symptoms. Changes in body-ideal internalization from baseline to 1-month follow-up completely mediated the relationship between condition and the changes observed in both ED and MD symptoms.

conclusionThese results provide further evidence of the efficacy of the tested intervention through 1-year follow-up in reducing body dissatisfaction and MD symptoms, but no such result was observed for body-ideal internalization and EDs. Our findings provide support for theoretical models of eating pathology and MD symptoms in Brazilian men.
