Risk Factors of Low Back Pain Among Railway Track-Maintainers in India: A Cross-Sectional Survey.
Article in Journal of chiropractic medicine, 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
Objectives: The objective of this study was to determine the relationship between low back pain (LBP) and ergonomic and psychosocial risk factors encountered by railway track maintainers in India. Methods: A cross-sectional survey was conducted in India. Socio-demographics, ergonomics, and psychosocial risk factors were examined among railway track maintainers. A modified Nordic Musculoskeletal Disorder Questionnaire was also administered to participants. The working posture of the participants was assessed using the Ovako Working Posture Analysis System (OWAS). Univariate logistic regressions were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) among participants. Results: 90.3% of railway track maintainers reported low back pain. In the univariate analysis, repetitive work (OR-2.848; 95% CI-1.34-6.051), awkward posture (OR-33.84; 95% CI-12.334-92.896), pulling loads (MMH) (OR- 6.300; 95% CI-2.802 to 14.166), and long working hours (OR- 4.553; 95% CI-1.910 to 10.854) all demonstrated significant relationships with LBP among participants. Psychosocial factors, such as work demand targeting specific productivity (97.3%), monotony of work (91.8%), perceived inadequacy of income (83.3%), and rigidity in work methods (86.4%), have a relationship with LBP. According to the OWAS posture analysis, most of the working postures of railway track maintainers require immediate correction. Conclusions: The high prevalence of LBP among railway track maintainers and its significant associations with ergonomic and psychosocial risk factors indicate a need to follow suggested preventive measures to avoid LBP.
