Occupational class differences in pancreatic cancer survival: A population-based cancer registry-based study in Japan.
Article in Cancer medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 2 of them syntheses that pooled it.
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
backgroundLittle is known about occupational class differences in pancreatic cancer survival.
methodsUsing a population-based cancer registry in Japan, 3 578 patients with incident pancreatic cancer (1970-2011) were followed up for 5 years (median follow-up time 0.42 years). We classified patients into four occupational classes based on their longest-held jobs: white-collar (professional and managers), service, blue-collar, and those not actively employed. Using white-collar class as the reference group, hazard ratios (HRs) and 95% confidence intervals (CIs) for overall death were estimated by Cox proportional hazard model. Covariates included age, sex, and year of diagnosis. Prognostic variables (pathology, stage, and treatment) and smoking behaviors were additionally adjusted as possible mediating factors.
resultsOverall survival was poor in this population (median, 0.50 and 0.33 years in white-collar and service classes, respectively). Compared with white-collar patients, survival was significantly poorer across all occupational classes, most pronounced in the service worker group: mortality HRs ranged from 1.11 (95% CI 1.00-1.24) in blue-collar workers to 1.24 (95% CI 1.12-1.37) in service workers. Even after controlling for potential mediating factors, service workers showed worse survival.
conclusionWe documented occupational class disparities in pancreatic cancer survival in Japan. Even in the setting of lethal prognostic cancer with universal health coverage, high-occupational class groups may enjoy a health advantage.
