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

We evaluate the evidence of cryptic speciation in Larimus breviceps, a species widely distributed in the western South Atlantic, from the Greater Antilles to Santa Catarina in Brazil. Mitochondrial (COI, Cyt b, and Control Region) and nuclear (IGF1 and Tmo-4C4) sequences were obtained from populations in the western South Atlantic. The analysis revealed two genetically distinct, sympatric lineages with no gene flow, with L. breviceps lineage II (LII) being closer to Larimus pacificus than to the L. breviceps lineage I (LI). The most recent common ancestor (TMRCA) for the L. breviceps LI and L. pacificus/L. breviceps LII clade dates from 12.3 Ma, whereas TMRCA for the L. pacificus and L. breviceps LII dates from 3.4 Ma, indicating that speciation processes may be related to the rise of the Isthmus of Panama. Despite these profound genetic differences, morphometric analyses found only subtle differences between lineages, with specimens of the LI being slightly larger than those of the LII, suggesting the existence of cryptic species. Within each lineage there is a pattern of panmixia within the study area. Therefore, we suggest that it is necessary a taxonomic revision of Larimus from the western Atlantic to validate the species status of such lineages.
