Global Estimates of COVID-19 Morbidity and Mortality: A Cohort Study and Mathematical Model Analysis.
Article in Influenza and other respiratory viruses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundThe true extent of the severity and fatality caused by the COVID-19 pandemic remains uncertain. This study provides an approximate estimate of the global disease burden from the pandemic.
methodsA cohort study followed the Qatari population from the onset of the pandemic to March 18, 2024, to estimate the age-specific incidence rates of severe, critical, and fatal COVID-19, classified according to World Health Organization criteria. A mathematical model then utilized these rates to generate regional and global estimates of COVID-19 severity and fatality.
resultsThe incidence rate of any severe, critical, or fatal COVID-19 throughout the pandemic was 1.13 (95% CI: 1.07-1.19) per 1000 person-years, while that of fatal COVID-19 alone was 0.11 (95% CI: 0.09-0.13) per 1000 person-years. Globally, the number of severe, critical, or fatal COVID-19 cases was estimated at 61.9 million (95% UI: 55.0-69.9 million), while the number of fatal COVID-19 cases alone was estimated at 11.3 million (95% UI: 7.8-17.4 million). Both estimates showed large regional variations. Most severe, critical, and fatal COVID-19 cases occurred during the pre-Omicron phase of the pandemic.
conclusionsThe COVID-19 pandemic had a profound global impact on morbidity and mortality, emphasizing the critical need for preparedness for future pandemics.
