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

A few families of retrotransposons characterized by the presence of long terminal repeats (LTRs) have amplified relatively recently in maize and account for >50% of the genome. Surprisingly, none of these elements have been shown to cause a single mutation. In contrast, most of the retrotransposon-induced mutations isolated in maize are caused by the insertion of elements that are present in the genome at 2-50 copies. To begin to understand what limits the amplification of this mutagenic class of LTR-retrotransposons, we are focusing on five elements previously identified among 17 mutations of the maize waxy gene. One of these elements, Stonor, has sustained a deletion of the entire gag region and part of the protease domain. Missing sequences were recovered from larger members of the Stonor family and indicate that the deletion probably occurred during retrotransposition. These large elements have an exceptionally long leader of 2 kb that includes a highly variable region of approximately 1 kb that has not been seen in previously characterized retrotransposons. This region serves to distinguish each member of the Stonor family and indicates that no single element has yet evolved that can attain the very high copy numbers characteristic of other element families in maize.
