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

purposeDescribe a new species of Spauligodon Skrjabin, Schikhobalova, and Lagodovskaja, 1960, parasitizing Thecadactylus rapicauda (Houttuyn, 1782) in Brazilian Amazon.

methodsA total of 40 host specimens were collected, anesthetized, and necropsied to search for helminths. The adult nematodes were collected, killed, and preserved in 70% ethanol. Specimens of both sexes were examined under a light microscope and a scanning electron microscope.

resultsThe diagnosis of the new species was based on a set of characteristics: the number of caudal spines in both males and females, absence of a spicule, number and arrangement of cloacal papillae in males, egg shape, and vulva position in females. We provide an identification key to the species from the Neotropical and Panamanian realms. We also analyzed the egg morphology in the species description of Spauligodon and proposed a classification for egg morphology and shape.

conclusionsSpauligodon caxiuana n. sp. is the 56th species of the genus, the fourth for the Neotropical realm, the third species record of Spauligodon spp. in Brazil, and the first in the Brazilian Amazon.
