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

In most organisms, the mismatch repair (MMR) system plays an important role in substantially lowering mutation rates and blocking recombination between nonidentical sequences. In Saccharomyces cerevisiae, the products of three genes homologous to Escherichia coli mutS-MSH2, MSH3, and MSH6-function in MMR by recognizing mispaired bases. To determine the effect of MMR on single-base pair mismatches, we have measured reversion rates of specific point mutations in the CYC1 gene in both wild-type and MMR-deficient strains. The reversion rates of all of the point mutations are similar in wild-type cells. However, we find that in the absence of MSH2 or MSH6, but not MSH3, reversion rates of some mutations are increased by up to 60,000-fold, whereas reversion rates of other mutations are essentially unchanged. When cells are grown anaerobically, the reversion rates in MMR-deficient strains are decreased by as much as a factor of 60. We suggest that the high reversion rates observed in these MMR-deficient strains are caused by misincorporations opposite oxidatively damaged bases and that MMR normally prevents these mutations. We further suggest that recognition of mispairs opposite damaged bases may be a more important role for MMR in yeast than correction of errors opposite normal bases.
