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 previously shown that there is an excess of sites that are polymorphic at orthologous positions in humans and chimpanzees and that this is most likely due to cryptic variation in the mutation rate. We showed that this might be a consequence of complex context effects since we found significant heterogeneity in triplet frequencies around coincident single nucleotide polymorphism (SNP) sites. Here, we show that the heterogeneity in triplet frequencies is not specifically associated with coincident SNPs but is instead driven by base composition bias around CpG dinucleotides. As a result, we suggest that cryptic variation in the mutation rate is truly cryptic, in the sense that the mutation rate does not appear to depend on any specific primary sequence context. Furthermore, we propose that the patterns around CpG dinucleotides are driven by the mutability of CpG dinucleotides in different DNA contexts. We also show that the genomic distribution of coincident SNPs is nonuniform and that there are some subtle differences between the distributions of single and coincident SNPs. Furthermore, we identify regions that contain high numbers of coincident SNPs and suggest that one in particular, a region containing the gene PRIM2, may be under balancing selection.
