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

Trematodes of the family Accacoeliidae Odhner, 1911 are well known as parasites of sunfishes. Herein, we report the accacoeliid trematode fauna of two sunfish species, Mola mola (Linnaeus) and Masturus lanceolatus (Liénard), in Japanese waters. Between 2023 and 2025, four individuals of each host species were examined, yielding 497 trematodes. These trematodes specimens were assigned to ten accacoeliid species (497 individuals in total) belonging to five genera through morphological and molecular analyses based on partial sequences of the nuclear 28S ribosomal RNA and mitochondrial cytochrome c oxidase subunit I genes. Four of the ten species were identified as new to science: Accacladocoelium latens n. sp., Accacladocoelium mayosenase n. sp., Accacladocoelium mica n. sp., and Rhynchopharynx yarimanbou n. sp. Detailed morphological descriptions were also provided for six known species: Accacladium serpentulum Odhner, 1928; Accacoelium contortum (Rudolphi, 1819); Accacladocoelium nigroflavum (Rudolphi, 1819); Accacladocoelium petasiporum Odhner, 1928; Odhnerium calyptrocotyle (Monticelli, 1893); and Rhynchopharynx paradoxa Odhner, 1928. Furthermore, Accacladocoelium alveolatum Robinson, 1934 was synonymized with Accacladocoelium nigroflavum based on molecular and morphological evidence.
