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

The Saccharomyces cerevisiae nonsense-mediated mRNA decay (NMD) pathway targets mRNAs with premature stop codons and some wild-type mRNAs for accelerated decay. Upf1p, Upf2p and Upf3p are required for NMD. NMD-targeted mRNAs are degraded rapidly in wild-type cells and stabilized in upf1, upf2 or upf3 mutants. We report here that the relative CYH2 pre-mRNA/mRNA accumulation is enhanced in cells derived from a W303 background, compared with a variety of commonly used strains. The enhanced CYH2 pre-mRNA accumulation phenotype results from a larger difference in mRNA half-lives in the W303 strains than two previously used strains. This phenotype can be selected in crosses and is also seen in upf2 and upf3 mutants. These results suggest there are genes that influence the efficiency of NMD and that yeast strains derived from the W303 background may be useful for measurement of abundance and half-lives of low abundance, short-lived NMD substrates.
