Obesity modifies the association of race and COVID-19 mortality: analysis of a retrospective cohort from Brazil.
Article in Scientific reports, 2024. 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
COVID-19 and obesity are two concurrent, interrelated pandemics that share similarities in their social causes, including racism. It is essential to understand how their characteristics are interrelated and the possible role of obesity in the association between race and COVID-19 mortality. We investigated the relationship between race and COVID-19 mortality and the modifying effect of obesity on this relationship. It is a retrospective cohort study. We analyzed data from 113,737 adults aged ≥ 19 years hospitalized for COVID-19 in Rio Grande do Sul, Brazil. The study outcome was in-hospital COVID-19 mortality. Exposures included race, analyzed as white, Brown, and Black individuals and as white vs. Brown and Black individuals, and obesity. The cumulative incidence of COVID-19 mortality was 33.46% (95% CI 33.18-33.74). Compared with white individuals, Brown individuals had a 39% higher likelihood of death from COVID-19 (95% CI 1.28-1.52), while Black individuals had a 30% higher likelihood (95% CI 1.20-1.41). Brown women with obesity had the greatest likelihood of COVID-19 mortality (1.64 [95% CI 1.27-2.13]) compared with all other groups. Obesity was an effect modifier of the association between race and COVID-19 mortality, increasing the likelihood of mortality in the group of Brown women.
