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

objectivesThe rise of flexible and diverse work schedules has become increasingly common in modern society. This study aims to investigate whether non-standard work schedules are related to sleep difficulty and other aspects of health-related quality of life (HRQoL) in Korea, with special attention to gender differences.

methodsData from the 2019 and 2021 National Health and Nutrition Examination Survey (Phase 8) were used, with a final sample consisting of 6735 participants. Ordinal logistic regression analysis was performed on sleep difficulty and the other seven items of the Health-related Quality of Life Instrument with 8 items (HINT-8) to examine associations with work schedules. Linear regression analysis was also conducted using the HINT-8 index as a composite measure.

resultsNon-standard work schedules were associated with a higher likelihood of sleep disturbances compared to the standard daytime work schedule. In particular, the negative impact of the night work schedule on sleep was greater for women than for men. Women working under the night work schedule were 12.2 percentage points more likely to report severe sleep difficulty than women under the day work schedule (9.6%). Additionally, the working, happiness, and vitality items of the HINT-8 were negatively associated with the night work schedule, whereas the other HINT-8 items and the HINT-8 index did not exhibit similar results.

conclusionsNon-standard work schedules are associated with increased sleep difficulty, particularly among women, and negatively affect several aspects of HRQoL, including vitality, happiness, and work performance. Given their rising prevalence and adverse impact on workers' sleep, health, well-being, as well as workplace safety and performance, non-standard work schedules should be recognized as a significant public health concern.
