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 aimed to examine the association between sleep duration on weekdays and weekends and depression among Korean adults.
designCross-sectional study.
settingSouth Korea, utilizing data from 2016 and 2018 Korea National Health and Nutrition Examination Survey (KNHANES).
participantsA total of 7669 South Korean adults aged 19-64 years. MEASURES: Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Sleep duration was classified separately for weekdays and weekends and categorized into three groups: <7, 7-9, and ≥9 h. Multiple logistic regression analysis was performed, adjusting for socioeconomic, lifestyle, and health-related variables.
resultsAmong the participants, 3.6% were identified as having depression. On weekdays, 40.5% of respondents reported an average sleep duration of less than 7 h per day, whereas only 20.3% did so on weekends. Compared to those who averaged 7 to less than 9 h of sleep per day, individuals with short sleep duration (<7 h) on weekdays had significantly higher odds of depression (OR: 1.65; 95% CI: 1.16-2.35), as did those with short sleep on weekends (OR: 1.62; 95% CI: 1.10-2.38). Notably, participants who consistently averaged less than 7 h of sleep per day across both weekdays and weekends demonstrated the highest odds of depression (OR: 1.76; 95% CI: 1.13-2.75).
conclusionsShort sleep duration on both weekdays and weekends was found to be associated with depression. These findings suggest that sleep duration should be considered an important factor in the prevention of depression.
