Trends in the incidence of cancers of the male genital system and urinary bladder in Harare, Zimbabwe, 1990-2019.
Article in Cancer causes & control : CCC, 2025. 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
purposeThe cancer registry of Harare, Zimbabwe, founded in 1986 allows the study of the evolution of the cancer epidemic in a Black (African) population over a 30-year period, and is used to investigate trends in the incidence of cancers of the male genital system and urinary tract.
methodsAge standardised incidence rates (ASRs) in the black (African) population of Harare are calculated for four cancers: prostate, testis and penis in men, and bladder in both sexes. Trends are expressed as the average annual percentage change in incidence.
resultsThe incidence of prostate cancer is very high (an ASR of 71.4 per 10
conclusionWhile some of these trends are related to population-level changes in lifestyles, and exposure to environmental factors (such as HPV), the reasons for other changes in incidence are more obscure. Some may be in part due to improvements in diagnostic techniques (endoscopy and imaging), but others-e.g. bladder-merit further investigation.
