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

The present study evaluated the phylogenetic relationships and the population structure in the 'Macrobrachium amazonicum' species complex, including M. amazonicum and M. pantanalense based on Single Nucleotide Polymorphism (SNP) markers. We analyzed specimens from three main genetic lineages (Clade I: M. amazonicum - Santarém-PA; Clade III: M. amazonicum - Mosqueiro-PA; Clade II: M. pantanalense - Bela Vista de Goiás-GO) and one artificially isolated population (M. amazonicum - Tucuruí-PA). After ddRAD sequencing, a final set of 969 SNPs were genotyped for all populations/species. High levels of genetic structure were observed among the populations of M. amazonicum, particularly when individuals from inland freshwater habitats in Amazon were compared to those from coastal basins, reinforcing the morphophysiological differences among both groups. Moreover, differently from the phylogenetic inferences using mitochondrial DNA markers, all analyses by SNPs confirmed the taxonomic status of M. pantanalense as a distinct species from M. amazonicum. Therefore, we provided the first molecular evidence of speciation in this group, being useful to resolve the taxonomic uncertainties in M. pantanalense. This study also indicates a putative process of ongoing speciation involving the clades I and III of M. amazonicum, thus emphasizing the need for further studies to better assess the relationships between both lineages.
