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

Instances of point and length heteroplasmy in the mitochondrial DNA control region were compiled and analyzed from over 5,000 global human population samples. These data represent observations from a large and broad population sample, representing nearly 20 global populations. As expected, length heteroplasmy was frequently observed in the HVI, HVII and HVIII C-stretches. Length heteroplasmy was also observed in the AC dinucleotide repeat region, as well as other locations. Point heteroplasmy was detected in approximately 6% of all samples, and while the vast majority of heteroplasmic samples comprised two molecules differing at a single position, samples exhibiting two and three mixed positions were also observed in this data set. In general, the sites at which heteroplasmy was most commonly observed correlated with reported control region mutational hotspots. However, for some sites, observations of heteroplasmy did not mirror established mutation rate data, suggesting the action of other mechanisms, both selective and neutral. Interestingly, these data indicate that the frequency of heteroplasmy differs between particular populations, perhaps reflecting variable mutation rates among different mtDNA lineages and/or artifacts of particular population groups. The results presented here contribute to our general understanding of mitochondrial DNA control region heteroplasmy and provide additional empirical information on the mechanisms contributing to mtDNA control region mutation and evolution.
