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
objectiveThis study evaluates the association between obesity and the presence of bowel endometriosis in patients undergoing surgery.
methodsA retrospective cross-sectional observational study was conducted with patients treated between September 2023 and December 2024, at a specialized endometriosis outpatient clinic of a tertiary hospital in Rio de Janeiro, Brazil. Women who underwent surgery for histopathological confirmation of deep endometriosis were included. The outcome was bowel endometriosis, defined as a lesion >1 cm located in the rectosigmoid region. Preoperative weight and height were measured, and obesity was defined according to World Health Organization body mass index (BMI) criteria. The association between obesity and the outcome was assessed using multivariable logistic regression, adjusting for potential confounders. A P-value <0.05 was considered statistically significant.
resultsA total of 223 women with histologically confirmed deep endometriosis were included, of whom 24.2% had bowel involvement. In the multivariable logistic regression, after adjusting for age and number of cesarean deliveries, body weight was independently associated with a lower likelihood of bowel lesions (odds ratio [OR]: 0.97; 95% confidence interval [CI]: 0.94-0.99; P = 0.031). The number of cesarean deliveries was also inversely associated with the outcome (OR: 0.39; 95% CI: 0.21-0.71; P = 0.002).
conclusionAlthough higher body weight was associated with a lower chance of bowel involvement, these results should be interpreted cautiously given the cross-sectional nature of the study and the limitations of BMI and body weight as measures of adiposity. Future studies incorporating more precise anthropometric assessments (e.g., bioimpedance, body fat percentage, or abdominal circumference) are warranted.
