1 · What the graph read from 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.

2 · The registry

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

The present study investigated the infection status of digenetic trematode metacercariae (DTM) in freshwater fish from Banbyeon-cheon in Yeongyang-gun, Gyeongsangbuk-do, Korea. A total of 211 freshwater fish representing 11 species were examined using the artificial digestion method in October 2023. Six taxa of DTM, including Clonorchis sinensis, Metagonimus spp., Centrocestus armatus, echinostomes, Exorchis oviformis, and Metacercaria hasegawai, were detected. The overall prevalence of DTM was 92.4% among the fish examined. The prevalence of C. armatus was the highest (52.8%), followed by E. oviformis (51.6%), M. hasegawai (35.6%), echinostomes (31.0%), C. sinensis (16.1%), and Metagonimus spp. (6.9%) in positive fish species. The infection intensity of C. armatus was 126 metacercariae per infected fish, whereas those of C. sinensis and Metagonimus spp. were 20 and 5.8 per infected fish, respectively. These findings indicate that at least 6 taxa of DTM, including C. sinensis and Metagonimus spp., are prevalent to varying degrees in fish from Banbyeon-cheon in Yeongyang-gun, Gyeongsangbuk-do, Korea. However, the potential risk of fishborne zoonotic trematodes, particularly C. sinensis, appears to be markedly lower than that reported in previous studies.
