Time worked in shifts and occurrence of drowsiness events while driving: attenuating effect of physical activity.

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
backgroundShift work disrupts circadian rhythms and is associated with adverse sleep outcomes, such as daytime sleepiness and drowsiness while driving. This study aimed to investigate the relationship between history of shift work, drowsiness events during driving, and the potential moderating effect of physical activity.
methodsA cross-sectional investigation involved 1,413 male shift workers in an iron ore mining firm. Heavy machinery essential to the mining process was operated. A specific question from the Berlin Questionnaire was used to evaluate drowsiness while driving, asking whether participants had ever felt drowsy or fallen asleep while driving, regardless of whether the episode occurred during work-related or leisure-time driving. The main explanatory variable was the shift in working hours. The levels of physical activity were classified as low, moderate, and high using the IPAQ. Multivariate and descriptive logistic regression analyses were conducted.
resultsThe majority of workers were aged 20 to 34 (45.1%), self-identified as non-white (77.2%), and had completed high school (76.0%). The average history of shift work time was 9.56 years (95% CI: 9.23-9.90), with 76% working for five years or more. Drowsiness events while driving were reported by 17.3% of workers. Multivariate analysis showed a significant association between history of shift work and drowsiness events, indicating a dose-response relationship, where longer history of shift work time increased the likelihood of drowsiness events (OR: 2.93 for 10-15 years; OR: 4.34 for > 15 years). However, physical activity acted as a moderating factor, demonstrating a dose-response effect in reducing this chance, with a reduction of 27.6% and 30.9% for moderate and high levels, respectively, compared to participants with a low level of activity.
conclusionA longer history of shift work time increases the chance of drowsiness events during driving, but higher physical activity levels mitigate them.
