Molecular analysis reveals a distinct subgenogroup of porcine epidemic diarrhea virus in northern Vietnam in 2018-2019.
Article in Archives of virology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The spike protein (S) of porcine epidemic diarrhea virus (PEDV), in particular, the C-terminal domain of the S1 subunit (S1-CTD), which contains the conserved CO-26K-equivalent (COE) region (aa 499-638), which is recognized by neutralizing antibodies, exhibits a high degree of genetic and antigenic diversity. We analyzed 61 PEDV S1-CTD sequences (630 nt), including 26 from samples collected from seven provinces in northern Vietnam from 2018 to 2019 and 35 other sequences, representing the G1a and 1b, G2a and 2b, and recombinant (G1c) genotypes and vaccines. The majority (73.1%) of the strains (19/26) belonged to subgroup G2b. In a phylogenetic analysis, seven strains were clustered into an independent, distinct subgenogroup named dsG with strong nodal support (98%), separate from both G1a and G1b as well as G2a, 2b, and G1c. Sequence analysis revealed distinct changes (513
