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

Human immunodeficiency virus type 1 (HIV-1) encodes a regulatory protein, Rev, which is required for cytoplasmic expression of incompletely spliced viral mRNA. Rev binds to a cis-acting Rev-responsive element (RRE) located within the env region of HIV-1. It has previously been shown that a 17-amino-acid peptide, corresponding to the basic domain of Rev, specifically inhibited in vitro the splicing of mRNAs containing the RRE. In this reaction, the peptide acts after an ATP-dependent step in the spliceosome assembly resulting in an accumulation of a 45-50S splicing-deficient complex. Characterization of this complex revealed that the basic domain of Rev does not interfere with U1 small nuclear ribonucleoprotein binding but blocks the entry of U4, U5, and U6 small nuclear RNAs into the spliceosome. Binding of U2 small nuclear ribonucleoprotein was partially inhibited. The critical nature of the oligomeric structure of RRE has been investigated both in vitro and in vivo. Reporter genes that contained one, three, or six repeated-monomer high-affinity Rev binding sites (IIB) within an intron yielded a correlation among the oligomeric state of bound Rev; inhibition of splicing; ability to block the assembly of U4, U5, and U6 small nuclear RNAs in the spliceosome in vitro; and level of Rev response in vivo.
