Development and application of whole-herd-sampling, qPCR-based-testing, and precision-removal methods to eliminate ASFV in four large swine herds in China.

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
Since the first ASFV case was reported in China in 2018, troditional control stategies involving whole-herd culling upon detection of ASFV positivity have proved unwieldy because of its high production intensity and complex trade network. To provide an alternative to conventional stamping-out methods, we developed a novel approach termed "Whole-herd-Sampling, qPCR-based-Testing, and Precision-Removal" method. This approach involves whole herd sampling and qPCR testing to determine the status of ASFV in herds, followed by the precision removal of identified infected sows. By applying these techniques, we successfully controlled ASF and eliminated the virus from 4 large swine herds between 2019 and 2020. The time to negative herd (TTNH) was 19, 28, 14, and 1 day from farm 1 to 4, respectively. Retention rates of pigs from farm 1 to farm 4 were 69.7%, 65%, 99.4%, and 99.72%, respectively. We propose that this innovative method would be a good alternative to the conventional stamping-out strategies and greatly facilitate the control and eradication of ASFV both in China and worldwide.
