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
Objectives: This study aimed to analyze the epidemiological characteristics of influenza virus circulation during the 2024-2025 season in the Republic of Korea (ROK), with a focus on recent trends in detection rates and subtype distribution. Methods: Weekly detection rates, subtype distribution, and age-specific patterns of influenza virus were analyzed using surveillance data from week 36 of 2024 to week 17 of 2025 as reported by the Korea Respiratory Virus Integrated Surveillance System. Results: ROK's 2024-2025 influenza season exhibited two distinct epidemic waves. The first wave began in late 2024 and peaked in week 1 of 2025, with a detection rate of 62.9%, representing a 20-30% increase compared to previous seasons. During this period, a notable increase in detection was observed among individuals over age 50, with influenza A viruses predominating. The second wave emerged in March 2025 and was driven by an increase in influenza B virus detection, which accounted for more than 50% of all influenza cases. The circulation of B virus was particularly prominent among school-aged children (7-18 years) and lasted longer than previous seasons. Conclusions: The 2024-2025 influenza season was characterized by increased detection levels compared with prior seasons, prolonged circulation of influenza B viruses, and a marked rise in infections among older adults. These findings suggest an ongoing shift in population immunity following the coronavirus disease 2019 pandemic. To respond effectively to the evolving patterns of respiratory virus circulation, the Korea Disease Control and Prevention Agency will continue to strengthen its timely detection and response efforts through enhanced surveillance systems.
