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

Ty1 retrotransposon RNA has the potential to fold into a variety of distinct structures, mutation of which affects retrotransposition frequencies. We show here that one potential functional structure is located at the 5' end of the genome and can assume a pseudoknot conformation. Chemoenzymatic probing of wild-type and mutant mini-Ty1 RNAs supports the existence of such a structure, while molecular genetic analyses show that mutations disrupting pseudoknot formation interfere with retrotransposition, indicating that it provides a critical biological function. These defects are enhanced at higher temperatures. When these mutants are combined with compensatory changes, retrotransposition is restored, consistent with pseudoknot architecture. Analyses of mutants suggest a defect in Ty1 reverse transcription. Collectively, our data allow modeling of a three-dimensional structure for this novel critical cis-acting signal of the Ty1 genome.
