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

Riboswitches are non-coding RNA motifs that regulate gene expression in response to ligand binding. The glycine tandem riboswitch (GTR) contains two glycine aptamers that interact extensively, driving conformational changes in the downstream expression platform to control gene expression. Despite numerous studies, the role of glycine and RNA folding pathways in co-transcriptional regulation remains unclear. Here, we integrate single-molecule kinetic analysis, co-transcriptional RNA structure probing, and modeling to reveal that the GTR processes multiple molecular inputs sequentially, guided by polymerase pausing. Our findings elucidate its stepwise 5'-to-3' folding pathway and demonstrate how sequential glycine binding to each aptamer, K
