Molecular Identification and Phylogenetic Analysis of Heterakis dispar Isolated from Geese.
Article in Acta parasitologica, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
purposeHeterakidosis is a common parasitic infection caused in domestic birds by Heterakis species: Heterakis gallinarum, H. isolonche, and H. dispar. Among them, the best described species is H. gallinarum, noted mainly in gallinaceous birds. In waterfowl, H. dispar is the predominant species. The variations in morphology and host specificity qualify H. dispar as a different species, but the phylogenetic relationships between heterakids were unclear for a long time, because of a lack of H. dispar sequences.
methodsThe authors provided the molecular data for H. dispar and analyzed the obtained sequences of the partial 18S rRNA gene and region ITS1-5.8SrRNA-ITS2 with the homological sequences.
resultsThe 18S rRNA PCR product of H. dispar was about 800 bp, and the ITS-5.8S-ITS2 PCR product was about 920 bp, noticeably smaller size compared to H. gallinarum product. The BLAST analysis of H. dispar 18S sequence showed a 99% similarity with the sequences of Heterakis gallinarum and Ascaridia galli, 98% with A. nymphii, but only 94% with the sequence of Heterakis sp. Our ITS sequence of H. dispar was almost identical to the H. isolonche isolate, there is only one nucleotide of difference among the 943 sites analyzed. It also showed a lower similarity to the ITS sequences of H. gallinarum (88%), H. spumosa (87%), and H. dahomensis (87%).
conclusionsIn our phylogenetic analysis, it is the first attempt at the reconstruction of relationships within this superfamily Heterakoidea based on 18S rDNA and ITS region.
