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
purposeThis study investigates the association between weekend catch-up sleep (CUS) and overweight/obesity in Korean adolescents, focusing on weekday sleep sufficiency.
methodsA nationwide cross-sectional study was conducted among 12,434 high school students in South Korea. Sleep patterns including total sleep duration and weekend CUS were assessed using self-reported questionnaires. Body mass index (BMI) was calculated and categorized into overweight/obese and normal weight groups based on age- and sex-adjusted Z-scores. Logistic and linear regression models were used to assess the associations between sleep variables and overweight/obesity.
resultsStudents with 3 or more h of CUS had lower odds of being overweight/obesity (odds ratio = 0.67, 95% confidence interval: 0.57-0.80) compared to those with non-CUS. This protective effect remained significant in the subgroup with perceived insufficient weekday sleep. Furthermore, students with 3 or more h of CUS had significantly lower BMI z-scores (β = -0.18, p < 0.001), an association that was also observed in those with perceived insufficient sleep (β = -0.16, p = 0.003). The analysis showed a dose-dependent pattern, with greater weekend CUS being associated with a stepwise reduction in BMI z-scores.
conclusionsWeekend CUS may serve as an important compensatory mechanism for adolescents to reduce the risk of being overweight or obese. However, no additional benefits of CUS were observed in adolescents with sufficient sleep quality.
