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

The Human Immunodeficiency Virus type-1 rev protein binds with high affinity to a bubble structure located within the rev-response element (RRE) RNA in stemloop II. After this initial interaction, additional rev molecules bind to the RRE RNA in an ordered assembly process which requires a functional bubble structure, since mutations in the bubble sequence that reduce rev affinity block multiple complex formation. We have used synthetic chemistry to characterize the interaction between rev protein and its high affinity binding site. A minimal synthetic duplex RNA (RBC6) carrying the bubble and 12 flanking base pairs is able to bind rev with 1 to 1 stoichiometry and with high affinity. When the bubble structure is inserted into synthetic RNA molecules carrying longer stretches of flanking double-stranded RNA, rev forms additional complexes resembling the multimers observed with the RRE RNA. The ability of rev to bind to RBC6 analogues containing functional group modifications on base and sugar moieties of nucleoside residues was also examined. The results provide strong evidence that the bubble structure contains specific configurations of non-Watson--Crick G:G and G:A base pairs and suggest that high affinity recognition of RRE RNA by rev requires hydrogen bonding to functional groups in the major groove of a distorted RNA structure.
