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
This report analyzes the characteristics of coronavirus disease 2019 (COVID-19) cases collected through mandatory surveillance between January 20, 2020 and August 30, 2023, by age, sex, and region. During the mandatory surveillance period, 34,572,554 cases, 35,605 deaths, and 38,112 severe/critical cases were recorded. The number of COVID-19 cases gradually increased in 2020 and 2021; however, the cases surged, with 82.2% of the pandemic's total cases reported in 2022, after the omicron variant became the dominant strain in January 2022. In March 2022, 9,959,368 cases were reported, accounting for the highest proportion (28.8%) of total cases. Individuals in their 40s (15.1%) and 30s (14.7%) represented the highest proportion of cases during the study period. Annually, the highest proportion of cases in 2020, 2021, 2022, and 2023 were observed among individuals in their 50s, 20s, 40s, and 30s, respectively. Regionally, metropolitan region accounted for 52.1% of the total cases. In non-metropolitan regions, most cases in 2020 were reported in Daegu and Gyeongbuk and increased in Busan, Ulsan, and Gyeongnam thereafter. This report complies with and conveys information on the characteristics of COVID-19 cases reported during the mandatory surveillance period. This report may serve as a reference for future respiratory infectious disease crises.
