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 transcriptases (RTs) of retroviruses and long terminal repeat (LTR)-retrotransposons possess DNA polymerase and RNase H activities. During reverse transcription these activities are necessary for the programmed sequence of events that include template switching and primer processing. Integrase then inserts the completed cDNA into the genome of the host cell. The RT of the LTR-retrotransposon Tf1 was subjected to random mutagenesis, and the resulting transposons were screened with genetic assays to test which mutations reduced reverse transcription and which inhibited integration. We identified a cluster of mutations in the RNase H domain of RT that were surprising because they blocked integration without reducing cDNA levels. The results of immunoblots demonstrated that these mutations did not reduce levels of RT or integrase. DNA blots showed that the mutations did not lower the amounts of full-length cDNA. The sequences of the 3' ends of the cDNA revealed that mutations within the cluster in RNase H specifically reduced the removal of the polypurine tract (PPT) primer from the ends of the cDNA. These results indicate that primer removal is not a necessary component of reverse transcription. The residues mutated in Tf1 RNase H are conserved in human immunodeficiency virus type 1 and make direct contact with DNA opposite the PPT. Thus, our results identify a conserved element in RT that contacts the PPT and is specifically required for PPT removal.
