A molecular phylogenetic study of the caecal fluke of poultry, Postharmostomum commutatum (= P. gallinum) (Trematoda: Brachylaimidae).
Article in Parasitology research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Postharmostomum commutatum (Dietz, 1858), a parasite of the caeca of poultry, has been reported from many different parts of the world. Despite its importance, there are no molecular sequences available and its phylogenetic position is unknown in relation to other members of Brachylaimoidea, a group in which taxonomic confusion reigns. Here, morphological and molecular techniques were used to study digeneans from the caeca of free-range chickens found naturally infected in the municipality of Viçosa, state of Minas Gerais, Brazil, between August 2017 and May 2018. The specimens were identified as P. commutatum, with Postharmostomum gallinum Witenberg, 1923 herein considered a junior synonym. Sequences obtained for the 28S, ITS2, and cox-1 genes were compared with sequences available from other species of Brachylaimoidea. Phylogenetic analysis of the three markers indicates P. commutatum formed an isolated lineage from other brachylaimoids, supporting the distinct status of the genus. The topology of phylogenetic trees obtained suggests that the morphology-based classification of families of Brachylaimoidea is artificial and new rearrangements of some genera or creation of new families may be necessary. The sequences newly obtained here will be useful for testing the cosmopolitan distribution of P. commutatum.
