Development of an indirect enzyme-linked immunosorbent assay based on nucleocapsid protein for the detection of swine acute diarrhea syndrome coronavirus antibody.
Article in Virology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundSwine acute diarrhea syndrome coronavirus (SADS-CoV) is a porcine enteric coronavirus that induces watery diarrhea in pigs, causing substantial economic losses in the swine industry. While the molecular and serological epidemiology of SADS-CoV in China has been extensively studied, comprehensive epidemiological studies assessing its prevalence outside China are lacking.
resultsIn this study, an indirect enzyme-linked immunosorbent assay based on the SADS-CoV N protein (N-iELISA) was developed to evaluate the seroprevalence of SADS-CoV in Korean pig herds. The optimal conditions for N-iELISA were determined through checkerboard titration of serum samples verified via western blotting. The assay showed sufficient specificity and reproducibility, with a cutoff value of 0.484. A total of 540 field samples collected from pig herds across nine provinces in Korea were subsequently tested using the N-iELISA. The findings revealed an overall seroprevalence of SADS-CoV in Korea of 8.70%.
conclusionsThese results indicate that the N-iELISA is a reliable tool for seroepidemiological studies of SADS-CoV and suggest that the seroprevalence of SADS-CoV in the Korean pig population is relatively low.
