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

Retroviruses selectively package two copies of their RNA genomes in the context of a large excess of nongenomic RNA. Specific packaging of genomic RNA is achieved, in part, by recognizing RNAs that form a poorly understood dimeric structure at their 5' ends. We identify, quantify the stability of, and use extensive experimental constraints to calculate a 3D model for a tertiary structure domain that mediates specific interactions between RNA genomes in a gamma retrovirus. In an initial interaction, two stem-loop structures from one RNA form highly stringent cross-strand loop-loop base pairs with the same structures on a second genomic RNA. Upon subsequent folding to the final dimer state, these intergenomic RNA interactions convert to a high affinity and compact tertiary structure, stabilized by interdigitated interactions between U-shaped RNA units. This retroviral conformational switch model illustrates how two-step formation of an RNA tertiary structure yields a stringent molecular recognition event at early assembly steps that can be converted to the stable RNA architecture likely packaged into nascent virions.
