Comparative analysis of the lethality pattern of Covid-19 and the response of BRICS countries to the pandemic in the context of multilateralism: An ecological study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
backgroundThis article analyzes the pattern of lethality due to Covid-19 in the BRICS countries and its conditioning factors, analyzing its temporal evolution, as well as analyzing the response given by the grouping to the health crisis as a multilateral forum.
methodsThis ecological time-series study assessed the lethality due to Covid-19 in the BRICS countries from March 2020 to May 2023. Using the Joinpoint method, and the temporal trend analysis of the lethality rates by segmented regression for each BRICS country.
resultsIn Brazil, the highest case fatality rate (8%) occurred in phase 1 (from April 27, 2020 to November 10, 2020), despite the peak in cases (1.2 million/week) in phase 3 (from December 31, 2021 to April 21, 2022). In Russia, phase 2 (from September 20, 2020 to March 7, 2021), which had the lowest incidence, had the second highest case fatality rate (4.5%). In India, the peak in cases in phase 2 (from March 13, 2021 to July 19, 2021) did not coincide with the peak in case fatality in the same phase. In China, the highest case fatality rate (12%) occurred in phase 1 (from March 10, 2022 to March 24, 2022), not reflecting the incidence. In South Africa, at the end of 2022, the fatality rate achieved was around 4.5%. DISCUSSION: The lethality of Covid-19 among BRICS countries showed differences related to failures in testing capacity, death information systems and access to vaccines. The group did not achieve the expected performance at an extremely opportune moment to demonstrate to the world their differential as representatives of emerging powers.
