Serum lipids and low back pain in male aircraft maintenance technicians: association after ergonomic exposure adjustment.
Article in Journal of occupational health, 2026. 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
objectivesTo explore the independent associations between serum lipids and low back pain (LBP) among male aircraft maintenance technicians after adjustment for ergonomic exposures.
methodsThis cross-sectional study enrolled 1713 male aircraft maintenance technicians. LBP and ergonomic exposures were assessed using the Chinese Musculoskeletal Questionnaire and Quick Exposure Check, respectively. We measured fasting serum lipids, including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Associations were examined using binary and ordinal logistic regression models with sequential adjustments for personal and occupational covariates.
resultsThe prevalence of LBP was 42.4%. After adjustment for potential confounders, the natural logarithm of TG (ln-TG) was positively associated with LBP presence (odds ratio [OR] 1.229; 95% CI, 1.020-1.480; P = .030) and intensity (OR 1.301; 95% CI, 1.097-1.542; P = .003), whereas HDL-C was inversely associated with LBP presence (OR 0.639; 95% CI, 0.438-0.932; P = .020). Categorical analysis identified key factors associated with higher LBP presence, including work experience of 5-9.9 years, high/very high back exposure, moderate/high work pace, high/very high stress, and borderline-high/high TG. The adjusted ORs for these key ergonomic exposures were higher than those for any lipid parameter.
conclusionsAmong male aircraft maintenance technicians, serum TG is an independent correlate of LBP after adjustment for ergonomic exposures. Given that ergonomic exposures are the predominant associated factors, prevention strategies should primarily focus on ergonomic interventions, with the management of serum lipids such as TG an adjunctive measure.
