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
This study aimed to examine the associations between insufficient sleep and health outcomes, specifically depressive symptoms and obesity, using data from the 2020 Korea National Health and Nutrition Examination Survey (KNHANES) with a cross-sectional study design. A total of 5912 participants (2648 men and 3264 women) were included. Among them, 823 individuals (13.9 %) experienced difficulty with weekday sleep deprivation, and 442 individuals (7.5 %) exhibited weekday-weekend sleep mismatch. The mean sleep duration varied according to age group, underlying disease, and physical activity level. Individuals with sleep deprivation were more likely to have depressive symptoms (OR 3.21, 95 % CI 2.65-3.90) and obesity (OR 1.29, 95 % CI 1.07-1.754). On the basis of these findings, both the duration and regularity of sleep are associated with depressive symptoms and obesity, suggesting that sleep patterns may play important roles in these health outcomes.
