A new type of tandem repeats in Myotis petax (Chiroptera, Vespertilionidae) mitochondrial control region.
Article in Molecular biology reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
backgroundTandem repeats in mitochondrial DNA control region are known to different animal taxa, including bat species of the family Vespertilionidae. The long R1-repeats in the bat ETAS-domain are often presented in a variable copy number and may exhibit both inter-individual and intra-individual sequence diversity. The function of repeats in the control region is still unclear, but it has been shown that repetitive sequences in some animal groups (shrews, cats and sheep) may include parts of ETAS1 and ETAS2 conservative blocks of mitochondrial DNA. METHODS AND
resultsAnalysis of the control region sequences for 31 Myotis petax specimens allowed the identification of the inter-individual variability and clarification of the composition of the R1-repeats. The copy number of the R1-repeats varies from 4 to 7 in individuals. The specimens examined do not exhibit a size heteroplasmy previously described for Myotis species. The unusual short 30 bp R1-repeats have been detected in M. petax for the first time. The ten specimens from Amur Region and Primorsky Territory have one or two copies of these additional repeats.
conclusionsIt was determined that the R1-repeats in M. petax control region consist of parts of the ETAS1 and ETAS2 blocks. The origin of the additional repeats seems to be related to the 51 bp deletion in the central part of the R1-repeat unit and subsequent duplication. Comparison of repetitive sequences in the control region of closely-related Myotis species identified the occurrence of incomplete repeats also resulting from the short deletions, but distinct from additional repeats of M. petax.
