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
backgroundPorcine teschovirus (PTV) is an important enteropathogen, associated with symptoms of polioencephalomyelitis, pneumonia, pericarditis, myocarditis, diarrhea, and reproductive disorders in pigs. Rapid and precise diagnostic methods are essential for managing PTV infections. The study introduced a simple, quick, and visual approach for detecting PTV through the use of RT-RAA coupled with LFD.
resultsThe procedures of RT-RAA-LFD for PTV could be carried out with 1.0 μmol/L primer concentration and 2.0 μmol/L probe concentration at 37 °C for 20 min, and the amplification result could be visualized within 5 min through LFD detection. Meanwhile, the assay established in this study showed no interaction with other associated diarrhea viruses, and has high specificity to PTV, with a minimal detection limit of 10 copies/μL and good repeatability. 128 clinical samples suspected of having a PTV infection were tested by RT-PCR and RT-RAA-LFD, respectively. The total diagnostic coincidence rate was 98.44% (126/128) with a Kappa value of 0.96(K ≥ 0.75), demonstrating a high degree of agreement to detect PTV for the two methods.
conclusionsThe RT-RAA-LFD assay created in this research displayed quick response, specificity, and sensitivity, capable of successfully detecting PTV in less than 25 min, providing an easy-to-use diagnostic instrument for rapid and visual PTV detection, especially suitable for labs and low-resource environments.
