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 previously reported that three alleles of the maize waxy (wx) gene were alternatively spliced as a result of the insertion of retrotransposons into intronic sequences. In addition, inefficient splicing of element sequences with the surrounding intron produced wild-type transcripts that presumably were responsible for the observed residual gene expression in the endosperm. In this study, we report that one of these alleles, wxG, has a tissue-specific phenotype with 30-fold more WX enzymatic activity in pollen than in the endosperm. Quantification of wxG-encoded transcripts in pollen and the endosperm demonstrates that this difference can be accounted for by tissue-specific differences in RNA processing. Specifically, there is approximately 30-fold more correctly spliced RNA in pollen than in the endosperm. Based on an analogy to similar examples of tissue-specific alternative splicing in animal systems, we hypothesize that the tissue-specific phenotype of the wxG allele may reflect differences in the concentration of splicing factors in these tissues.
