1 · What the graph read from 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.

2 · The registry

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

backgroundDementia incidence is rising globally with population aging and improved survival from chronic diseases. Cancer incidence may reflect longevity, diagnostic capacity, socioeconomic development, and demographic transition, but sex-specific population-level evidence on its association with dementia incidence remains limited.

methodsCountry-level associations between cancer incidence in 2019 and dementia incidence in 2023 were examined separately for females and males across 204 countries. Analyses included bivariate correlations, principal component analysis, partial correlations, and forced-entry regression models adjusted for gross domestic product per capita adjusted for purchasing power parity, urbanization, reduced selection opportunity, and sex-specific life expectancy at age 60.

resultsCancer incidence was positively associated with dementia incidence in both sexes. Globally, cancer incidence correlated strongly with dementia incidence among females (r = 0.765, p < 0.001) and males (r = 0.781, p < 0.001). In adjusted models, cancer incidence remained associated with dementia incidence in females (β = 0.496, p < 0.001; adjusted R

conclusionsCancer incidence is a sex-specific country-level correlate of dementia incidence. Findings indicate population-level co-variation, not individual-level risk or causality in aging populations worldwide.
