Epidemiological investigation of avian infectious bronchitis and locally determined genotype diversity in central China: a 2016-2018 study.
Article in Poultry science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Infectious bronchitis (IB), caused by avian IB virus (IBV), is an acute and highly contagious disease of chickens. From 2016 to 2018, 56 IBV strains were isolated and identified from clinical samples obtained from various chicken farms located in central China. The S1 sequencing of these strains revealed nucleotide and amino acid identities of 70.2 to 100% and 62.6 to 100%, respectively, compared with those of reference strains. Phylogenetic analysis indicated that the genotypes of the isolates included GI-13 (4/91), GI-7 (TW-I), GI-24 (Mass), GI-19 (QX), and GI-18 (LDT3-A), with GI-19 (QX) being the predominant genotype. Meanwhile, GI-13 (4/91) was the second most dominant genotype in Henan Province, whereas it was GI-7 (TW-I) in Hunan and Hubei provinces. Recombination analysis of 3 variant strains showed that CK/CH/HeN/20160113 might be a recombination of LDT3-A- and QX-type strains and that CK/CH/HeN/20160316 might be a recombination of Italy-02-type strain and CK-CH-LJS08II. The predicted tertiary structure between CK/CH/HeN/20160113 and LDT3-A-type strain revealed that the novel 336 (L-P) and 455 (S-A) mutations changed the structure from an alpha helix to a random crimp. In addition, the 275 (Y-F) site reduced the length of the β-sheet, whereas the site 353 (A-T) extended the β-sheet. These findings suggested that GI-19 (QX) remains the predominant genotype in central China, and a locally determined complex genotype associated with variable clinical symptoms exists related to gene recombination and mutations.
