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
Objective: To compare the associations between sleep quality and body mass index (BMI), as well as excess weight status, in male and female subjects, while exploring potential mediating factors, including lifestyle and health-related variables. Materials and Methods: The present cross-sectional study analyzed data from 5,260 (29.7% male and 70.3% female) Brazilian adults collected through a virtual survey applied from 2023 to 2024. Sleep quality and duration were assessed using the Pittsburgh Sleep Quality Index (PSQI). The BMI was derived from self-reported weight and height, with excess weight defined as BMI > 24.9 kg/m Results: Among the female subjects, poor sleep quality (β = 0.46; 95%CI: 0.15-0.77) and short sleep duration (β = 0.62; 95%CI: 0.27-0.97) were associated with higher BMI and 21% of increased odds of excess weight after adjusting for all covariates (age, depression, chronic conditions, level of schooling, marriage status, smoking, alcohol consumption, screen time before bed, physical activity, diet quality, and whether dinner is the largest meal of the day). The mediation analysis showed that chronic conditions (20%), depression (16%), and diet quality (14%) mediated the total effect of poor sleep quality on BMI in female participants. Screen time before bed was the only significant mediator for short sleep duration, accounting for ∼ 5% of the total effect. No significant associations were found in male subjects. Conclusion: Our findings highlight sex differences in the relationship between sleep and BMI, emphasizing the need for sex-specific approaches to sleep and weight management, focusing on health and lifestyle improvements.
