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 17-3 RNA aptamer recognizes DMHBI and induces its fluorescence. We showed that the 17-3 RNA aptamer predominantly induced emission of the phenolate form of DMHBI. We also demonstrated that the active structure of the minimal form of the 17-3 aptamer possessed three stem elements and two large loop elements, which we named Karashi and its sequence-optimized variant, Jigarashi, respectively. Chemical modification experiments suggested that the two loop regions formed tertiary interactions and/or non-Watson-Crick base pairs, and no remarkable structural alterations occurred upon DMHBI binding. AlphaFold3 also predicted a tertiary structure of the ligand-free form of Jigarashi RNA, which was consistent with the results of chemical modification experiments.
