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

This study reports trematode infection in tadpoles at early developmental stages under natural conditions. While most previous records describe infections in more advanced stages, we identified metacercariae of the diplostomid Neodiplostomum sp. in tadpoles of five anuran species at the Gosner stage between 25 and 28. A total of 207 tadpoles from eight species (Families Hylidae and Leptodactylidae) were collected from seasonal water bodies from Brazil, of which 39 were found parasitized with helminths. Within this group of infected tadpoles, 20 were specifically parasitized by trematodes, 12 of them at the earliest stages of tadpole development (Gosner stage 25). This record indicates that tadpole infection with trematodes may occur earlier than previously documented, providing new insights into the infection dynamics of larval trematodes.
