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

backgroundPorcine circovirus 4 (PCV4), a newly emerging virus that was first discovered in 2019, may pose a potential threat to the pig industry. Droplet digital PCR (ddPCR) is an absolute quantitative method that has high sensitivity and accuracy. In this study, we developed a novel ddPCR assay to detect PCV4. Furthermore, we evaluated the detection limit, sensitivity, specificity and reproducibility of the ddPCR and TaqMan real-time quantitative PCR (qPCR) and tested 160 clinical samples to compare the detection rate of the two methods.

resultsThe detection limit for ddPCR was 0.54 copies/µL, 10.6 times greater sensitivity than qPCR. Both ddPCR and qPCR assays exhibited good linearity and repeatability, and the established ddPCR method was highly specific for PCV4. The results of clinical sample testing showed that the positivity rate of ddPCR (5.6%) was higher than that of qPCR (4.4%).

conclusionsThis study successfully developed a sensitive, specific and repeatable ddPCR assay for PCV4 detection, which can be widely used in clinical diagnosis of PCV4 infections.
