Genetic Characterization and Evidence of Capsid Epitope Variation in Porcine Circovirus Type 3 Strains from Vietnamese Swine with Reproductive Disorders.
Article in Current microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This study investigated the presence and genetic diversity of porcine circovirus type 3 (PCV3) in Vietnam. Fifteen samples from sows with reproductive disorders across five provinces were screened by qPCR; those with Ct-values < 25 underwent sequencing. Whole-genome analysis revealed multiple polymorphisms, including a notable A24L substitution in the ORF2 Cap protein. Phylogenetic results showed 13 strains belonged to genotype PCV3b, while two were PCV3a (PCV3a-1 and PCV3a-IM), suggesting PCV3b predominance in Vietnam. Additionally, PCV3a-2 was significantly associated with respiratory and digestive disorders (p ≤ 0.001). These findings highlight PCV3's clinical relevance and support genotype-based classification for future vaccine and control efforts.
