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

Both the chloroplast and mitochondrial genomes are used extensively in studies of plant population genetics and systematics. In the majority of angiosperms, the chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA) are each primarily transmitted maternally, but rare biparental transmission is possible. The extent to which the cpDNA and mtDNA are in linkage disequilibrium is argued to be dependent on the fidelity of co-transmission and the population structure. This study reports complete linkage disequilibrium between cpDNA and mtDNA haplotypes in 86 individuals from 17 populations of Silene vulgaris, a gynodioecious plant species. Phylogenetic analysis of cpDNA and mtDNA haplotypes within 14 individuals supports a hypothesis that the evolutionary histories of the chloroplasts and mitochondria are congruent within S. vulgaris, as might be expected if this association persists for long periods. This provides the first documentation of the evolutionary consequences of long-term associations between chloroplast and mitochondrial genomes within a species. Factors that contribute to the phylogenetic and linkage associations, as well as the potential for intergenomic hitchhiking resulting from selection on genes in one organellar genome are discussed.
