Cancer incidence and mortality in the occupational cohort of a German toxic waste landfill: a retrospective cohort study.
Article in BMC public health, 2024. 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
backgroundEmployees at the Ihlenberg toxic waste landfill in northern Germany were found to have an increased risk of cancer and cancer-related deaths in previous analyses covering the time period from 1983 to 2008. The present study aimed to quantify cancer risk and all-cause mortality in the employee cohort in 2009 to 2021.
methodsIn this retrospective cohort study, cancers were identified by linkage with cancer registries, and employee deaths were obtained from population registries. Standardized incidence ratios (SIRs) for cancers and standardized mortality ratios (SMRs) were calculated to quantify cancer and mortality risk in the employee cohort. The effects of employment duration and different latency periods up to 30 years were additionally considered.
resultsThe cohort of 590 employees (432 men, 158 women) who worked at the landfill for at least 3 months between 1983 and 2018 was established from human resource management documentation and followed from January 1, 2009 until December 31, 2021. During this follow-up period, the SIR for all cancers combined was 0.69 (95% confidence interval (CI): 0.47, 0.98) and the SMR for all-cause mortality was 0.51 (95% CI: 0.35, 0.73). Longer employment at the landfill was not associated with increased cancer incidence or mortality.
conclusionsEmployment at the landfill, expected to reflect occupational exposure to toxic waste, was not associated with increased cancer incidence or mortality in the employee cohort. Preventive measures to reduce exposure and to promote a healthy lifestyle should be maintained at the landfill.
