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 study of mitochondrial DNA (mtDNA) variability at the level of whole mitogenomes has significant implications for the fields of human evolution and population genetics. In this paper, we present the results of a study of the complete mtDNA variability in Belarusians from the southeastern part of the Republic of Belarus. It was found that Southeast Belarusians are characterized by a high diversity of mitochondrial genomes. The analysis of genetic distances between European populations showed significant differences between the studied Belarusian sample from the bulk of East European populations, including Slavic ethnic groups. The results of the phylogeographic analysis indicated the presence of the West Asian component (12.6%) in the Belarusian mitochondrial gene pool, which can account for the observed genetic differences between Belarusians and other Eastern Slavs (Russians and Ukrainians). The East Asian component of the mitochondrial gene pool of the studied group of Belarusians is represented by haplogroup C5c1a (2.3%). The results of the phylogeographic analysis indicated that this mtDNA subclade is predominantly present in the gene pools of Slavic peoples, including Poles, Belarusians, Ukrainians, and Russians. The evolutionary age of haplogroup C5c1a is ~4000 years and, consequently, the appearance of C5c1-haplotypes in the eastern regions of Europe may be linked to the migrations of the Caspian steppe populations to the west during the Bronze Age.
