Health Problems, Unhealthy Behaviors and Occupational Carcinogens Exposures Among Night Shift Brazilian Workers: Results from National Health Survey, 2019.
Article in International journal of environmental research and public health, 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
introductionNight shift work (NSW) has been increasingly addressed in the scientific literature, as it is considered a probable carcinogen. In this study, we investigated the association of NSW with health problems, unhealthy behaviors, and occupational carcinogens.
methodsCross-sectional study with a sample of 47,953 workers from the 2019 National Health Survey. NSW prevalence was estimated according to sociodemographic characteristics. To investigate the associations of NSW with all study variables, gender stratified logistic regression models were used. The odds-ratio and 95% confidence intervals were estimated.
resultsAmong men, there was a significant association of NSW with sleep disorders (OR = 1.39; 95% CI: 1.17-1.65), tiredness (OR = 1.68; 95% CI: 1.41-2.00), obesity (OR = 1.41; 95% CI: 1.20-1.66), unhealthy food consumption (OR = 1.28; 95% CI: 1.12-1.46), handling of radioactive material (OR = 2.45; 95% CI: 1.61-3.72), and biological material (OR = 3.18; 95% CI: 3.15-4.80). Among females, NSW was associated with the same variables except obesity, but depressive feelings (OR = 1.35 95% CI: 1.09-1.67), frequent alcohol intake (OR = 1.48; 95% CI: 1.23-1.78), handling of chemical substances (OR = 1.54; OR = 1.54; 95% CI: 1.20-1.97), and passive smoking at work (OR = 1.45; 95% CI: 1.12-1.86) were highly significant.
conclusionNight shift workers are more vulnerable to occupational carcinogen exposure, experience greater impacts on their well-being, and are more likely to engage in unhealthy behaviors. These findings should be considered in managing and organizing night work in the workplace. Actions to promote healthy work environments should be encouraged to protect workers' health.
