Differences in mortality and incidence for major sites of cancer by education level in a Japanese population.
Article in Annals of epidemiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeWe aimed to examine the relationships between education and mortality and incidence for major sites of cancer in a Japanese population.
methodsSubjects were 32,883 respondents of questionnaire survey in 1978 with ages younger than 75 years. Cancer cases were ascertained through 2001, and causes of deaths were identified through 2003. Hazard ratios of deaths from cancer or developing cancers were compared among those with 9 or less, 10-12, and 13 years or more of education using Cox proportional hazard models.
resultsAs for cancer mortality of all sites combined, a statistically significantly decreasing trend was observed in age-adjusted models in both men and women, but no significant differences were observed in multivariate-adjusted (age, body mass index, smoking, radiation dose, and city) models. Among major cancer sites (stomach, colon/rectum, liver, lung, and female breast) examined, a significantly decreasing trend was observed for male liver cancer in a multivariate-adjusted model. As for incidence, a significantly decreasing trend was observed for cancer of all sites combined in men, and for male liver and prostate cancer and female lung cancer in a multivariate-adjusted model.
conclusionsEducational differences in cancer incidence and mortality were generally rather small, but were significant for incidence for male all-site, male liver, prostate, and female lung cancers.
