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

Two approximately 135-nucleotide (nt) direct repeats flank the Rous sarcoma virus (RSV) oncogene src and are composed of two smaller repeats, dr1 (approximately 100 nt) and dr2 (approximately 36 nt). These sequences have been reported to contain cis-acting signals necessary for RNA packaging and elements that allow cytoplasmic accumulation of unspliced RNA (cytoplasmic transport elements). In this report, we show that avian fibroblasts infected with the Prague A strain of RSV with precise deletions of both dr1 elements express src and are transformed by this mutant virus but production of virus particles is very low and virus spread throughout the culture requires several weeks. We show that the replication defect is due to complex effects on viral RNA transport, viral RNA half-life, and virus particle assembly. The dr1 elements may contain binding sites for a permissive cell-specific factor(s) that facilitates efficient nuclear-cytoplasmic transport, RNA stability, and cytoplasmic utilization of unspliced viral RNA. The implications of these results for understanding the defects of nonpermissive virus infections in mammalian cells are discussed.
