1 · What the graph read from it

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.

2 · The registry

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

To investigate the association between weekend catch-up sleep (WCS) duration and depressive symptoms among young adults in China and the United States, and to explore potential associated factors. We conducted a binational cross-sectional study comprising 1,440 Chinese young adults (collected in 2024) and 892 US young adults (from NHANES 2021-2023). Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9 ≥ 10). WCS duration was categorized. Logistic regression, restricted cubic splines (RCS), and threshold effect models were employed to examine the relationship. Subgroup analyses were conducted by sex, education, and lifestyle factors. A U-shaped association was observed in both populations. Compared to no catch-up sleep (0 h), a WCS duration of 0-1 h was associated with significantly lower odds of depressive symptoms (China: Odds Ratios (OR) = 0.495, 95% Confidence Intervals (CI) 0.339-0.724; US: OR = 0.412, 95% CI 0.209-0.812). Restricted Cubic Spline (RCS) and threshold analyses confirmed this non-linear pattern, with inflection points at approximately 0.58 h (China) and 1.01 h (US). Subgroup analyses indicated the associations were modified by sex and alcohol drinking status. This study reveals a consistent U-shaped association between WCS and depressive symptoms among young adults in two distinct national populations. Moderate weekend catch-up sleep (around 0-1 h) may be associated with lower odds of depressive symptoms. These findings highlight the importance of balanced sleep patterns for mental health in young adults.
