Genetic evolution of hemagglutinin and neuraminidase genes of H5N1 highly pathogenic avian influenza viruses in Thailand.
Article in PeerJ, 2022. 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
Background: Ongoing outbreaks of H5N1 highly pathogenic avian influenza (HPAI) viruses and the emergence of the genetic-related hemagglutinin ( Methods: Full-length nucleotide sequences of 178 Results: ML phylogenetic analysis revealed two distinct HA clades, clade 1 and clade 2.3.4, and two distinct NA groups within the corresponding H5 clade 1 viruses. Bayesian phylogenetic reconstruction for molecular clock suggested that the Thai H5N1 HA and NA emerged in 2001.87 (95% HPD: 2001.34-2002.49) and 2002.38 (95% HPD: 2001.99-2002.82), respectively, suggesting that the virus existed before it was first reported in 2004. The Thai H5N1 HA clade 2.3.4 was grouped into corresponding clades 2.3.4, 2.3.4.1, 2.3.4.2, and 2.3.4.3, and shared nucleotide similarities to reassortant H5Nx clade 2.3.4.4 ranged from 92.4-96.8%. Phylogenetic analysis revealed monophyletic H5Nx clade 2.3.4.4 evolved from H5N1 clade 2.3.4. Conclusion: H5N1 viruses existed, and were presumably introduced and circulated in avian species in Thailand, before they were officially reported in 2004.
