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 correlation between pathogen detection through wastewater-based infectious disease surveillance at airports and ports in the Chungcheong region and the incidence of corresponding infectious diseases in the local population. Methods: Between March and December 2024, 192 wastewater samples were collected from Gunsan Port, Pyeongtaek-Dangjin Port, and Cheongju International Airport. Eight infectious disease pathogens were analyzed using TaqMan Array Card-based multiplex detection. Next-generation sequencing was also conducted on selected samples positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to identify the Omicron sublineages. Results: Of the 192 samples, SARS-CoV-2 was detected in 101 (52.6%) and influenza virus in 38 (19.8%). The detection rates were higher at airports (SARS-CoV-2: 72.6%, influenza: 22.6%) than at ports (SARS-CoV-2: 37.0%, influenza: 17.6%). When comparing the monthly detection rates of SARS-CoV-2 and influenza with regional case counts, the SARS-CoV-2 detection rates increased in August and declined in September, showing a similar pattern to the trend in reported cases. In contrast, the influenza virus detection rates in wastewater increased in November, approximately one month earlier than the increase in reported influenza cases observed in December. Sequencing analysis of the SARS-CoV-2 samples identified variants KP.3, JN.1, and XEC, consistent with those reported in domestic patients. Conclusions: Wastewater-based surveillance at airports and ports can serve as an effective supplementary tool to symptom-based quarantine systems, enabling the earlier detection and prevention of the domestic spread of imported infectious diseases.
