Rapid detection of pigeon adenovirus 2 using a TaqMan real-time PCR assay.
Article in Poultry science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Pigeons infected with aviadenoviruses have been found worldwide. Recently, pigeon adenovirus 2 (PiAdV-2) has been widely distributed in racing pigeons in Germany. However, the epidemiology of this virus remains unclear due to the lack of a specific detection platform for PiAdV-2. In this study, we first detected PiAdV-2 positivity in racing pigeons (designated FJ21125 and FJ21128, which share 100% nucleotide identity with each other based on the fiber 2 gene) in Fujian, Southeast China. These genes shared 99.8% nucleotide identity with PiAdV-2 (GenBank No. NC_031501) but only 54.1% nucleotide identity with PiAdV-1 (GenBank No. NC024474). Then, the TaqMan-qPCR assay for the detection of PiAdV-2 was established based on fiber 2 gene characterization. The established assay had a correlation coefficient of 1.00, with an amplification efficiency of 99.0%. The minimum detection limit was 34.6 copies/μL. Only PiAdV-2 exhibited a positive fluorescent signal, and no signal was detected for other pathogens (including PiCV, FAdV-4, FAdV-8a, EDSV, PPMV-1, RVA and PiHV). The assay has good reproducibility, with a coefficient of variation less than 2.42% both intragroup and intergroup. The distributions of PiAdV-2 in fecal samples from YPDS (35 samples) and healthy (43 samples) racing pigeons from different geographical areas were investigated and were 37.14% (YPDS) and 20.93% (healthy), respectively. In summary, we developed a TaqMan-qPCR platform for the detection of PiAdV-2 infection with high sensitivity, specificity, and reproducibility. We confirmed the presence of PiAdV-2 in China, and our data suggested that there is no indication of a correlation between YPDS and PiAdV-2. This study provides more information on the pathogenesis mechanism and epidemiological surveillance of PiAdV-2.
