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

We have extended our previous analysis of the pedigree rate of control-region divergence in the human mitochondrial genome. One new germline mutation in the mitochondrial DNA (mtDNA) control region was detected among 185 transmission events (generations) from five Leber hereditary optic neuropathy (LHON) pedigrees. Pooling the LHON pedigree analyses yields a control-region divergence rate of 1.0 mutation/bp/10(6) years (Myr). When the results from eight published studies that used a similar approach were pooled with the LHON pedigree studies, totaling >2,600 transmission events, a pedigree divergence rate of 0.95 mutations/bp/Myr for the control region was obtained with a 99.5% confidence interval of 0.53-1.57. Taken together, the cumulative results support the original conclusion that the pedigree divergence rate for the control region is approximately 10-fold higher than that obtained with phylogenetic analyses. There is no evidence that any one factor explains this discrepancy, and the possible roles of mutational hotspots (rate heterogeneity), selection, and random genetic drift and the limitations of phylogenetic approaches to deal with high levels of homoplasy are discussed. In addition, we have extended our pedigree analysis of divergence in the mtDNA coding region. Finally, divergence of complete mtDNA sequences was analyzed in two tissues, white blood cells and skeletal muscle, from each of 17 individuals. In three of these individuals, there were four instances in which an mtDNA mutation was found in one tissue but not in the other. These results are discussed in terms of the occurrence of somatic mtDNA mutations.
