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: To investigate the differences in chronic disease prevalence and underlying metabolic profiles among working-age individuals across six typical occupational groups, identify occupation-related associated factors, and provide epidemiological evidence for occupation-specific precise prevention and control of chronic diseases. Methods: A cross-sectional study design was adopted. A total of 1,473 on-the-job physical examinees aged 18-64 who received physical examination at the Physical Examination Center of the First Hospital of Lanzhou University from August 2024 to August 2025 were retrospectively included. Structured questionnaires were distributed via targeted online channels to collect sociodemographic characteristics and behavioral and lifestyle data. Physical examinations and laboratory tests were performed to obtain 16 health indicators. Age-standardized prevalence (ASR) of five chronic diseases (hypertension, diabetes mellitus, hyperlipidemia, hyperuricemia, and obesity) was calculated using the direct standardization method, with the age composition of the full study sample as the standard population. Multivariate logistic regression analysis was conducted to assess the independent associations between various factors and chronic diseases, and Spearman rank correlation analysis was used to evaluate the strength of associations between health indicators. Results: Occupational disparities in the prevalence of hyperlipidemia and hyperuricemia were the most prominent. After age standardization, the prevalence of hyperlipidemia in police officers (ASR = 0.435, 95% CI 0.368-0.502) and software engineers (ASR = 0.418, 95% CI 0.366-0.470), as well as the prevalence of hyperuricemia in firefighters (ASR = 0.381, 95% CI 0.315-0.447) and police officers (ASR = 0.332, 95% CI 0.267-0.396) were all significantly higher than those in healthcare workers (ASR = 0.218 for hyperlipidemia and 0.143 for hyperuricemia, respectively), with no overlap in 95% CIs across occupational groups. Multivariate logistic regression analysis showed that police officers (OR = 2.499, 95% CI 1.409-4.433) and software engineers (OR = 2.531, 95% CI 1.007-6.361) were independent associated factors for hyperlipidemia; police officers (OR = 3.425, 95% CI 1.821-6.441), firefighters (OR = 4.143, 95% CI 1.916-8.955), and software engineers (OR = 2.957, 95% CI 1.136-7.696) were independent associated factors for hyperuricemia. No statistically significant occupational disparities were observed for hypertension, diabetes mellitus, and obesity. Correlation analysis showed that triglyceride, high-density lipoprotein cholesterol, body mass index, uric acid and alanine aminotransferase formed a moderate correlation cluster (| Conclusion: Police officers, firefighters, and software engineers are occupational groups with elevated prevalence of hyperlipidemia and hyperuricemia. Age standardization is a necessary methodological step for cross-occupational health comparisons. Obesity occupies a core hub position in the metabolic comorbidity network. These findings provide reference evidence for developing occupation-specific, tiered precise prevention and control strategies for chronic diseases.
