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

purposeThe present study provides an integrative redescription of Sprostoniella micrancyra Cezar, Luque and Amato, 1999 (Monopisthocotylea: Capsalidae), a parasite of the Atlantic spadefish, Chaetodipterus faber (Broussonet, 1782) (Actinopterygii: Ephippidae) off the southeastern Brazilian coast. An additional specimen of Sprostoniella lamothei Pérez-Ponce de Léon and Mendoza-Garfias, 2000 collected from Parapsettus panamensis (Steindachner, 1876) in Peru was included for comparative molecular assessments.

methodsS. micrancyra specimens were examined using light microscopy, histology, and scanning electron microscopy, with morphological preparations carried out following standard processing protocols. Genomic DNA was extracted from both Sprostoniella species, and partial sequences of the 28S rDNA and mitochondrial cox1 genes were generated. Phylogenetic relationships were inferred using Maximum Likelihood and Bayesian inference.

resultsMorphological observations of S. micrancyra revealed several previously unreported features, including the presence of a pair of accessory haptoral sclerites, a pair of anchors, a haptor with one central loculus, and the absence of a vaginal opening, contrasting with the original description. Scanning electron microscopy confirmed haptoral organization and detailed the structure of adhesive discs and peduncle musculature, while histology elucidated the organization of reproductive and attachment structures and muscular systems. Phylogenetic analyses of ribosomal and mitochondrial markers recovered the two Sprostoniella species as a monophyletic clade.

conclusionOur results expand current knowledge of S. micrancyra and underscore the importance of integrative approaches to clarify the taxonomy and evolutionary relationships of capsalids.
