The relationship between the dominant hand and neck/shoulder pain in the workplace: a prospective cohort study.
Article in Journal of occupational health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTo date, no studies have investigated the relationship between one's dominant hand and neck/shoulder pain. The aim of this prospective cohort study was to explore the relationship between one's dominant hand and the severity of neck/shoulder pain. We also examined the relationship between the dominant hand and the onset of neck/shoulder pain at follow-up among workers without neck/shoulder pain at baseline.
methodsWe conducted a prospective cohort study of 9451 workers. The dominant hand was measured by 10 items from the Japanese version of the Flanders Questionnaire at the baseline survey. We assessed neck/shoulder pain using a numeric rating scale. We calculated the unstandardized coefficient (B) using multiple regression analysis and the incidence rate ratio (IRR) for neck/shoulder pain using modified Poisson regression among workers who were free of neck/shoulder pain at baseline.
resultsAmong the 9451 respondents for the baseline survey, 6156 responded to the follow-up survey (response rate: 65.1%). Mixed-handed workers reported a higher degree of neck/shoulder pain than right-handed workers (B, 0.33; 95% CI, 0.09-0.58). Among 2481 participants, mixed-handed workers also had a higher IRR for neck/shoulder pain (IRR, 1.27; 95% CI, 1.01-1.61). There was no difference in any of the left-handers compared with the right-handers.
conclusionsThe study found that mixed-handed workers had higher levels of neck/shoulder pain than right-handed workers, and the incidence rate was also higher among mixed-handed workers. Employers should consider these findings when designing work environments, managing tasks, and providing occupational health training to optimize worker comfort and safety.
