Prevalence and multivariate analysis of risk factors associated with musculoskeletal disorders among automotive assembly workers: a cross-sectional study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMusculoskeletal disorders (MSDs) are a leading cause of occupational morbidity. This study investigates the prevalence and associated factors of MSDs across nine body regions among automotive parts assembly workers, considering demographic characteristics, mental workload, and Structured Multidisciplinary work Evaluation Tool (SMET) questionnaire components.
methodsThe cross-sectional study included 211 workers (41.2% female; mean age 33.9 ± 6.9 years). Demographic data, mental workload National Aeronautics and Space Administration-Task Load Index (NASA-TLX), and SMET questionnaire components (physical, environmental, and psychosocial demands) were collected. The Extended Nordic Musculoskeletal Questionnaire was used to assess MSD prevalence. Univariate and multivariate logistic regression analyses identified significant predictors.
resultsThe lifetime prevalence of MSDs was highest in the neck (44.5%) and lower back (44.1%), with the lowest rates in the elbow (6.8%) and hip/thigh (14.2%). Multivariate analyses revealed significant predictors of MSD prevalence. For neck disorders, male sex (OR = 0.361), smoking status (OR = 3.437), surgical history (OR = 2.800), total mental workload (OR = 1.032), and physical demand (OR = 1.396) were key contributors. Shoulder disorders were associated with smoking (OR = 2.542) and illness history (OR = 2.380), whereas upper back disorders were linked to illness history (OR = 3.287) and physical demand (OR = 1.663). Gender-specific vulnerabilities were evident in the hip/thigh and knee regions, with male gender being a significant predictor (hip/thigh: OR = 4.833; knee: OR = 2.711). Surgical history and psychosocial demands are critical factors for ankle/foot disorders.
conclusionsMSDs in assembly line workers result from the interaction of demographic, physical, and psychological factors.
