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

Although precluded from using splicing to produce multiple small Rep proteins, adeno-associated virus type 5 (AAV5) generates a Rep40-like protein by alternative translation initiation at an internal AUG. A defined region upstream of the internal AUG was both required and sufficient to program internal initiation within AAV5 and may act similarly in heterologous contexts. The internally initiated AAV5 Rep40-like protein was functional and had helicase activity similar to that of AAV2 Rep40. Surprisingly, both the AAV5 Rep40-like protein and Rep52 were able to be translated from the AAV5 upstream P7-generated RNAs; however, the relative level of small to large Rep proteins was reduced compared to that of the wild type. A P19 mutant AAV5 infectious clone generated near-wild-type levels of the double-stranded monomer replicative form (mRF) replicative intermediate but reduced levels of virus, consistent with the previously defined role of Rep40-like proteins in genome encapsidation. Levels of mutant virus were dramatically reduced upon amplification.
