The burden of bladder cancer and kidney cancer attributable to smoking in Latin America and the Caribbean from 1990 to 2023 and projections to 2050.
Article in Tobacco induced diseases, 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
introductionTobacco smoking is a major modifiable risk factor for bladder and kidney cancer. In Latin America and the Caribbean (LAC), comprehensive longitudinal evidence on the smoking-attributable burden of these cancers remains limited. This study assessed the burden, temporal trends, socioeconomic inequalities, and future projections of smoking-attributable bladder and kidney cancer in LAC.
methodsData were obtained from the Global Burden of Disease (GBD) 2023 study to estimate deaths, disability-adjusted life years (DALYs), age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR) for smoking-attributable bladder and kidney cancer across 33 countries and territories in Latin America and the Caribbean from 1990 to 2023. Temporal trends were evaluated using joinpoint regression and average annual percent change (AAPC). Socioeconomic inequalities were assessed in relation to the sociodemographic index (SDI) using the slope index of inequality (SII) and concentration index (CIX). Future burden to 2050 was projected using a Bayesian age-period-cohort model.
resultsIn 2023, smoking-attributable bladder cancer caused an estimated 1742 deaths and 35903 DALYs in LAC, while kidney cancer caused 637 deaths and 14947 DALYs. From 1990 to 2023, ASMR and ASDR for both cancers showed overall declining trends, although substantial regional heterogeneity was observed, with the Caribbean showing increasing burden. At the national level, the burden of both cancers was positively associated with SDI in 2023. Projections to 2050 indicate that age-standardized rates will continue to decline, whereas the absolute numbers of deaths and DALYs will increase.
conclusionsAge-standardized rates declined overall, whereas the absolute numbers of deaths and DALYs are projected to increase in Latin America and the Caribbean. Stronger tobacco control and better-prepared health systems are needed to address the growing cancer burden in aging populations.
