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

Although repair of double-strand breaks (DSBs) by gene conversion is the most accurate way to repair such lesions, in budding yeast there is a 1,000-fold increase in accompanying mutations, including interchromosomal template switches (ICTS) involving highly mismatched (homeologous) ectopic sequences. Although such events are rare and appear at a rate of 2 × 10(-7) when template jumps occur between 71% identical sequences, they are surprisingly frequent (0.3% of all repair events) when the second template is identical to the first, revealing the remarkable instability of repair DNA synthesis. With homeologous donors, ICTS uses microhomologies as small as 2 bp. Cells lacking mismatch repair proteins Msh6 and Mlh1 form chimeric recombinants with two distinct patches of microhomology, implying that these proteins are crucial for strand discrimination of heteroduplex DNA formed during ICTS. We identify the chromatin remodeler Rdh54 as the first protein required for template switching that does not affect simple gene conversion.
