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
purposeIntuitive exercise may foster healthier engagement in physical activity, leading to enhanced well-being and more intuitive eating habits. The Intuitive Exercise Scale (IEXS) was originally developed to assess this construct in English speakers. The IEXS is composed of four scales addressing distinct facets of intuitive exercise: emotional exercise, body trust, exercise rigidity, mindful exercise. The present study aimed to validate an Italian translation of the IEXS, exploring its factorial structure, invariance, internal consistency, and convergent validity.
methodsA sample of 1140 women and men (age: M = 45.25, SD = 11.64, range 22-76 years) was recruited from the Italian general population; 61.8% were physically active. Inclusion criteria were being an Italian native speaker and being at least 18 years. The sample was randomly split in two equal halves for the Exploratory Factor Analysis (n = 570; women: 50%; physically active: 61.8%) and the Confirmatory Factor Analysis (n = 570; women: 50%; physically active: 61.8%). Multi-group confirmatory factor analyses were performed to assess invariance among women and men and physically and non-physically active individuals. McDonald's omega was used to assess internal consistency. Pearson's correlations were utilized to assess convergent validity.
resultsThe Italian IEXS replicated a four-factor structure and showed good invariance among women and men. Invariance among physically and non-physically active individuals was only partially supported. Excellent internal consistency and adequate convergent validity were achieved.
conclusionsThe IEXS demonstrated to be a valid measure to examine intuitive exercise in the Italian population, replicating and expanding the findings of the English version. Level of evidence Level V, Cross-sectional, Psychometric study.
