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 assess the incidence, mortality and epidemiological-demographic profile of severe acute respiratory syndrome and deaths among confirmed COVID-19 cases in Indigenous populations between 2020 and 2021.
methodsThis is a descriptive study based on COVID-19 data provided by the Ministry of Health's Indigenous Health Secretariat. COVID-19 incidence and mortality in Brazil were analyzed. The analysis included creation of graphs and maps and calculation of hospitalization rates.
resultsIncidence of severe cases varied between the Indigenous Health Districts (116.3 to 2,034.1 per 100,000 inhabitants), with the highest rates in the Kaiapó do Pará (2,034.1 per 100,000 inhabitants), Leste de Roraima (1,632.6 per 100,000 inhabitants) and Alto Rio Juruá (1,601.8 per 100,000 inhabitants) Districts. Comparing 2020 and 2021, there was a 64.9% reduction in the number of severe cases, from 4,520 in 2020 to 1,585 in 2021. In 2020, 27.1% of deaths occurred without hospitalization, decreasing to 18.8% in 2021. The majority of severe cases occurred in the 20-39 age group (30.6% in 2020 and 30.7% in 2021), and the highest concentration was in the Northern region of Brazil (69.7% in 2020 and 55.0% in 2021).
conclusionThe high incidence of severe cases and the high proportion of deaths without hospitalization highlight challenges in combating COVID-19 among Indigenous populations. The concentration of cases in the Northern region reinforces the need for specific strategies for this region.
