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 study aimed to examine the relationship between occupational factors and sleep disorders among employees in petrochemical enterprises. MATERIAL AND

methodsAll participants from the employees of Hainan Petroleum Refining and Chemical Enterprises were recruited by the cluster sampling in June 1, 2022. The questionnaire used in this research was primarily composed of 3 sections: demographic characteristics,

resultsA total of 952 valid questionnaires were collected. The frequency of sleep disorders among the 952 participants was 41.9% (N = 399). After PSM, 356 pairs were successfully matched. There was no statistical difference in socio-demographic characteristics between sleep disorder groups (p > 0.05). The logistic regression analysis showed that employees with weekly working time >40 h exhibited a higher likelihood of sleep disorders (OR: 1.74, 95% CI: 1.09-2.82) than those working ≤40 h. Individuals exposed to high-temperature working environments were more likely to experience sleep disorders (OR: 1.77, 95% CI: 1.12-2.81), while the sleep disorder risk in those with occupational stress was 2.67-fold (OR: 2.67, 95% CI: 1.89-3.80). Employees in storage and transportation (OR: 3.34, 95% CI: 1.81-6.40) and other positions (OR: 1.68, 95% CI: 1.03-2.75) displayed a higher risk of sleep disorders than operational workers.

conclusionsThe frequency of sleep disorders among employees in petrochemical enterprises is high. Weekly working hours, type of work position, high-temperature exposure, and high occupational stress are associated with increased risk of sleep disorders among petrochemical workers. Health policymakers should fully consider these factors in improving the sleep quality of petrochemical workers. Int J Occup Med Environ Health. 2024;37(6):591-601.
