Increased Risk of Influenza-Like Illness Clusters in Schools, Taiwan from 2011 to 2020: A Retrospective Study.
Article in Journal of epidemiology and global health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Acute influenza-like illnesses (ILIs) are primarily caused by influenza type A or type B viruses. Several factors influence the risk of the spread of ILIs. The present study investigated the epidemiological characteristics, differences, and epidemiological trends of influenza viruses, noninfluenza respiratory pathogens, and locations where clusters occurred in Taiwan between 2011 and 2020. The study analyzed publicly available data on 1,545 confirmed ILI clusters, with the data obtained from the Taiwan Centers for Disease Control. In total, 1,334 ILI clusters were caused by influenza virus infection, 11 ILI clusters were caused by noninfluenza respiratory pathogens, and 78 ILI clusters were caused by pathogens not detected in routine testing. Additionally, for 122 ILI clusters, no pathogen detection was initiated. Significant differences were observed (p < 0.001) in the number of ILI clusters between influenza and noninfluenza respiratory pathogens in 2011-2020. In addition, significant differences were observed (p < 0.001) in the number of ILI clusters between locations in 2011-2020. In terms of specific pathogens within ILI clusters, single infections with influenza A virus accounted for the highest number of cases (69.6%, 1076/1358, odds ratio: 1.740-2.957, p < 0.001-0.012), followed by adenovirus infections among noninfluenza respiratory pathogens (58.3%, 7/12). Schools had the highest number of ILI clusters (47.3%, 731/1545) among the investigated institutions (odds ratio: 1.438-1.556, p < 0.001-0.012). This study provides valuable insights into ILI cluster transmission patterns in Taiwan over a 10-year period and highlights the importance of long-term studies covering a wide geographic area as a means of understanding the implications of such patterns.
