Near complete 12S DNA reference library for the freshwater fish of French Guiana, northern Amazonian region.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
The limited availability of DNA reference libraries is a key limitation to developing biodiversity inventories using environmental DNA techniques. This dataset provides a 12S mitochondrial DNA reference library covering 88.92% of the species of freshwater fish inhabiting French Guiana. It contains 1,557 references, covering 369 species distributed across 51 families. It also covers the intraspecific diversity of most of these species. DNA was extracted from 1,439 specimens collected during over 25 field expeditions. DNA collections from museum records were used to complement the data for a further 118 specimens. The sequences cover two widely used eDNA primers for fishes (Teleo1 and 12S-V5) enabling identification of most Guianese freshwater fish species using eDNA metabarcoding. Beyond French Guiana, the dataset covers 6.31% of Neotropical fish species, 23.05% of genera, and 56.04% of families, making it valuable for broader regional studies. This dataset provides a comprehensive and reliable DNA reference library for the Neotropical fish, filling an important biodiversity gap in a remote, biodiversity-rich region that is difficult to sample.
