An epidemiological investigation of porcine circovirus type 2 and porcine circovirus type 3 infections in Tianjin, North China.
Article in PeerJ, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Novel porcine circovirus type 3 (PCV3), first identified in the United States, has been detected in many other countries. Porcine circovirus is associated with postweaning multisystemic wasting syndrome, reproductive failure, congenital tremors, and other clinical symptoms. In this study, we established a double polymerase chain reaction assay for detecting both porcine circovirus type 2 (PCV2) and PCV3. This is the first study to detect and characterize the PCV3 genome in the Tianjin region of North China. We collected a total of 169 tissue samples from seven farms between 2016 and 2018. The PCV3-positive rate of all tissue samples was 37.3% (63/169) and the rate of PCV2 and PCV3 coinfection was 14.8% (25/169). PCV2 and PCV3 coinfections with more serious clinical symptoms were found in only three farms. We sequenced three PCV3 strains selected from tissue samples that were positively identified. The complete genome sequences of the three strains shared 97.6-99.4% nucleotide identities with the PCV3 strains in GenBank. Our results showed the extent of PCV3's spread in Tianjin, and the need to further study PCV3's pathobiology, epidemiology, isolation, and coinfection.
