Projections of colorectal cancer mortality to 2040 in Mexico and their association with socioeconomic status.
Observational study in Cancer causes & control : CCC, 2026. 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
purposeAnalyze colorectal cancer (CRC) mortality trends in Mexico from 2000 to 2023, evaluate its association with socioeconomic status (SES), and project estimated mortality to 2040.
methodsWe conducted a retrospective, observational analytical study using the Mexican National Mortality registries. We calculated the age-adjusted mortality rate using the direct method of standardization and the WHO standard population. We projected death rates using an ARIMA model (0, 1, 1). Socioeconomic status was stratified into three tiers using the Municipal Social Deprivation Index. A negative binomial regression model was employed, adjusting for age, sex, and year.
resultsBetween 2000 and 2023, 116,135 deaths due to CRC were registered, with a consistent annual increase. The overall age-adjusted mortality rate increased by 44.1%, being higher for men (58.7%) than for women (36.3%). The projections for 2040 estimate a rate of 7.63 deaths per 100,000 persons (95% CI 5.71-9.56). The multivariate analysis demonstrates a progressive increase in mortality risk over time. A lower SES is associated with a 13% increase in mortality risk compared to higher SES (p < 0.001).
conclusionsCRC mortality in Mexico has increased significantly with disparities due to sex, age, and socioeconomic status. The findings underline the urgency for the implementation of early detection strategies and oncological attention, especially within vulnerable populations, with the intention of closing gaps in access and improving outcomes for colorectal cancer.
