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

Plus-strand RNA viruses serve as templates for translation and then transcription by newly synthesized RdRp. A ribosome-binding tRNA-shaped structure (TSS) and upstream hairpin H4 in the 3' UTR of Turnip crinkle virus (TCV) play key roles in translation and transcription. Second-site mutations generated to compensate for altering the critical asymmetric internal loop of H4 included a three- to two-base alteration in the terminal loop of a 3' proximal hairpin (Pr) located downstream of the TSS. Unlike the non-deleterious three-base alteration, single mutations in Pr loop were detrimental for RdRp transcription while enhancing translation and RdRp binding. One deleterious mutation in the Pr loop altered the structures of both the TSS and H4. These complex interactions in the 3' UTR support a compact structural arrangement likely permitting RdRp access to a number of residues within a 195-base region including the 3' end that are necessary for efficient transcription initiation.
