1 · What the graph read from it

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.

2 · The registry

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

introductionHexostoma auxisi Palombi, 1943 was originally described by Palombi (1943) from Auxis thazard off Italy, Mediterranean Sea. The original description of this species lacks morphological and morpho-metrical data. In addition, no published sequence of this species is available in molecular engines. MATERIALS AND

methodsSpecimens of Hexostoma auxisi were collected from the gills of Auxis rochei (Risso, 1810) off the Algerian coast, Western Mediterranean. Monogenean were stained with acetic carmine, measured and drawn. Furthermore, molecular study was conducted using partial fragment of the mitochondrial cytochrome c oxidase subunit 1 (cox1) of parasites and a tissue sample of the fish's gills on which the monogeneans were found.

resultsIn this study, we provide morpho-anatomical and morpho-metrical data of Hexostoma auxisi. Our specimens are morphologically close to those described by Palombi (1943) off Italy, Mediterranean Sea. The morphological study was supported by a molecular analysis of cox1 gene that reveals that our sequence of H. auxisi is distinct from its congener H. thynni by 20.51%. CONLUSION: The present study allowed us to confirm the taxonomic status of Hexostoma auxisi which belongs to the genus Hexostoma and the family Hexostomatidae.
