COVID-19 among health care workers in Brazil: prevalence and disparities based on respondent-driven sampling.
Article in Revista de saude publica, 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
objectiveTo determine the prevalence and disparities of COVID-19 among health care workers in Brazil.
methodsA survey was conducted among health care workers in five Brazilian cities. Disparities in the prevalence of COVID-19 were analyzed by professional category and region (North/Northeast versus South/Southeast).
resultsThe sample was composed of 2,499 health care workers: 601 (24.1%) nursing technicians, 1,095 (43.8%) registered nurses, and 803 (32.1%) physicians. Recruitment and data collection were conducted online from May 21, 2020, to February 10, 2021, using respondent-driven sampling. The overall COVID-19 prevalence was 48.1% (95%CI: 43.4-52.9). The highest COVID-19 prevalence was identified among nursing technicians (52.8%; 95%CI: 44.4-61.0). Nursing technicians reported undergoing fewer PCR and COVID-19 tests compared to physicians. Nursing technicians and registered nurses in the North/Northeast regions who reported COVID-19 symptoms spent much of the first year of the pandemic without access to confirmatory testing. Furthermore, the risk of laboratory-confirmed COVID-19 was significantly lower for all occupational categories in the North and Northeast regions.
conclusionsCOVID-19 rates among health care workers were exceptionally high and non-uniformly distributed. This mirrors the vast socioeconomic, cultural, and political differences and the difficulty in coordinating pandemic control actions in Brazil.
