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

Gyrodactylus abbottinae n. sp. is described from the body surface of the Chinese false gudgeon Abbottina rivularis (Cyprinidae: Gobioninae) in China, supported by integrative morphological and molecular evidence. Morphologically, G. abbottinae n. sp. is distinguished from its congeners (G. rivularae and G. gobioninum) on the same host by the shape of marginal hooks sickle and ventral bar, and male copulatory organ structure. Although the marginal hook shape of G. abbottinae n. sp. resembles species of the wageneri-group (e.g., G. gobii and G. salaris), its haptoral structures are significantly smaller. Phylogenetic analysis based on ITS (ITS1-5.8S-ITS2) rDNA sequences revealed that G. abbottinae n. sp. forms a distinct lineage among G. parvae, G. pseudorasborae, G. gobii and G. gobiensis infecting Gobioninae fish, yet clusters within the subgenus G. (Limnonephrotus) alongside species parasitizing Cyprininae (G. kobayashii, G. gurleyi, G. longoacuminatus, G. sprostonae), Rhodeinae (G. rhodei, G. sinenorhodei, G. ocellorhodei and G. acheilorhodei) and Danioninae (G. banmae). The substantial ITS rDNA divergence between G. abbottinae n. sp. and its current phylogenetically related species exceeds conventional thresholds for closely related gyrodactylid species, suggesting probable undiscovered host switching events.
