Individual- and area-level socioeconomic inequalities in cancer incidence in the working-age population - a cohort study based on German statutory health insurance data, 2015 to 2019.

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
introductionCancer is a major public health challenge in Germany with significant socioeconomic inequalities in incidence and mortality. However, there is only limited research on the incidence of diagnosis-specific cancers and related inequalities among socioeconomic groups within the working-age population. This study aims to address this gap by analysing how the incidence of common cancers depends on individual- and area-level socioeconomic characteristics among working-age women and men.
methodsUsing a prospective cohort design based on anonymised German statutory health insurance data, this study examined a cohort of 2.23 million individuals aged 25-67 years over a five-year period (2015-2019). Individual socioeconomic position was assessed using educational attainment and occupational skill levels, while area-level deprivation was determined using a composite socioeconomic index. Incidence rates were estimated per 100,000 person-years at risk, age-standardised to the 2013 European standard population. Hazard ratios were calculated using multilevel Cox proportional hazards models.
resultsThe analysis revealed 50,276 newly diagnosed cancer cases during the study period. Lower education, lower occupational skill levels and higher area-level deprivation were associated with a higher incidence of stomach, lung, colorectal, prostate, breast and cervical cancer, but a lower incidence rate of malignant melanoma of the skin. After mutual adjustment of the socioeconomic indicators, higher hazard ratios of lung cancer were found for men with lower educational (HR = 2.8, 95%CI:2.3-3.5) and occupational skill levels (HR = 2.8, 95%CI:2.3-3.5) and for women with lower education (HR = 2.3, 95%CI:1.7-3.1). Lower occupational skill levels in both sexes (women HR = 0.6, 95%CI:0.5-0.7; men HR = 0.7, 95%CI:0.6-0.9) and lower educational levels in men (HR = 0.7, 95%CI:0.6-0.8) were independently associated with a lower risk of malignant melanoma. For area-level deprivation, we observed a higher risk of stomach (women 1.6, 95%CI:1.2-2.0; men HR = 1.3, 95%CI:1.1-1.6) and lung cancer (women HR = 1.3, 95%CI:1.1-1.5; men HR = 1.5, 95%CI:1.3-1.7) in more deprived areas, even after adjusting for individual-level socioeconomic characteristics. In contrast, a higher risk of skin melanoma was observed in less deprived areas after individual-level socioeconomic adjustments (women and men HR = 0.6, 95%CI:0.5-0.7).
conclusionsOur findings suggest that strategies to prevent cancer in the working-age population should take more account of the unequal structural conditions in which people work and live. The study shows that area-level socioeconomic deprivation has explanatory power for unequal cancer risks beyond the individual characteristics of socioeconomic position.
