The mitochondrial DNA molecule of the aardvark, Orycteropus afer, and the position of the Tubulidentata in the eutherian tree.

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
An outstanding problem in mammal phylogeny is the relationship of the aardvark (Orycteropus afer), the only living species of the order Tubulidentata, to the extant eutherian lineages. In order to examine this problem the complete mitochondrial DNA (mtDNA) molecule of the aardvark was sequenced and analysed. The aardvark tRNA-Ser (UCN) differs from that of other mammalian mtDNAs reported and appears to have reversed to the ancestral secondary structure of non-mammalian vertebrates and mitochondrial tRNAs in general. Phylogenetic analysis of 12 concatenated protein-coding genes (3325 amino acids) included the aardvark and 15 additional eutherians, two marsupials and a monotreme. The most strongly supported tree identified the aardvark as a sister group of a clade including the armadillo (Xenarthra) and the Cetferungulata (carnivores, perissodactyls, artiodactyls and cetaceans). By applying three molecular calibration points the divergence between the aardvark and armadillo-cetferungulates was estimated at ca. 90 million years before present.
