"Ancient DNA" reveals that the scientific name for an extinct tortoise from Cape Verde refers to an extant South American species.
Article in Scientific reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
We examined the type material of the extinct tortoise species Geochelone atlantica López-Jurado, Mateo and García-Márquez, 1998 from Sal Island, Cape Verde, using aDNA approaches and AMS radiocarbon dating. High-quality mitochondrial genomes obtained from the three type specimens support that all type material belongs to the same individual. In phylogenetic analyses using mitochondrial genomes of all species groups and genera of extant and some recently extinct tortoises, the type material clusters within the extant South American red-footed tortoise Chelonoidis carbonarius (Spix, 1824). Our radiocarbon date indicates that the tortoise from which the type series of G. atlantica originates was still alive during 1962 and 1974. These results provide firm evidence that the type material of G. atlantica does not belong to the Quaternary tortoise bones excavated on Sal Island in the 1930s, as originally thought. Thus, the extinct tortoise species remains unstudied and lacks a scientific name, and the name G. atlantica has to be relegated into the synonymy of C. carbonarius. The circumstances that led to this confusion currently cannot be disentangled.
