Association of Weekend Catch-Up Sleep With the Triglyceride/High-Density Lipoprotein Cholesterol Ratio.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeInsulin resistance affects more than just diabetes, influencing overall health. Weekend catch-up sleep (WCUS) might alleviate the adverse health outcomes of ongoing sleep deprivation. The triglyceride/high-density lipoprotein cholesterol (TG/HDL) ratio serves as an effective marker for insulin resistance. This study aimed to investigate the association between WCUS and the TG/HDL ratio according to gender and weekday sleep duration.
methodsWe analyzed nationwide data from the 2019-2021 Korean National Health and Nutrition Examination Survey (KNHANES), which included 10,562 participants: 4,611 male participants (43.7%) and 5,951 female participants (56.3%). Participants' sleep data were collected through self-reported questionnaires. WCUS was divided into the following categories: ≤0 hours, >0-1 hours, >1-2 hours, and >2 hours. Weekday sleep was categorized into three groups: ≤6 hours, >6-8 hours, and >8 hours.
resultsThe number of participants and their percentages for WCUS were as follows: 7,152 (62.7%) for ≤0 hours, 1,163 (11.6%) for >0-1 hours, 1,275 (14.3%) for >1-2 hours, and 972 (11.5%) for >2 hours. In multivariable analysis, WCUS (>2 hours) was inversely associated with the TG/HDL ratio (ß coefficient = -0.22, 95% confidence interval (CI): -0.38, -0.06, p = 0.006; odds ratio (OR) = 0.74, 95% CI: 0.57, 0.96, p = 0.031 for TG/HDL > 3.9), and with weekday sleep < 6 hours (OR = 0.68, 95% CI: 0.46, 0.99, p = 0.025). Considering gender differences, the association between WCUS (>2 hours) and the TG/HDL ratio showed a borderline inverse correlation, particularly among male participants (β = -0.41, 95% CI: -0.70, -0.12, p = 0.006; OR = 0.69, 95% CI: 0.51, 0.94, p = 0.052 for TG/HDL > 3.9; OR = 0.65, 95% CI: 0.41, 1.03, p = 0.087 for weekday sleep < 6). No significant association between WCUS (>2 hours) and the TG/HDL ratio was observed in female participants.
conclusionThe WCUS (>2 hours) had an inverse association with the TG/HDL ratio in male participants, which may have a beneficial effect on insulin resistance.
