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

Reverse transcription in the yeast retrotransposon Ty1 follows the general "rules" of retroviral replication overall. However, some details of the retroviral and Ty1 reverse transcription processes are different. We have identified and determined the structure of plus-strand strong-stop DNA and examined the effect of polypurine tract deletion mutations on its synthesis. Furthermore, we have defined the stop signal for plus-strand strong-stop DNA synthesis as an unusual 2'-O-ribosylated nucleotide in the primer tRNA. Full-length plus-strand strong-stop DNA, following strand transfer, would have a terminal 2-base mismatch with minus-strand DNA. These findings indicate that the mechanism of plus-strand strong-stop DNA transfer in Ty1 differs from that of the retroviral transfer and suggest that full-length plus-strand strong-stop DNA is not a direct intermediate in Ty1 retrotransposition.
