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

RNA structural heterogeneity is increasingly recognized as essential for RNA function, yet quantitative understanding of intrinsic RNA structural dynamics and how cellular conditions modulate these dynamics remains limited. 7SK RNA is an abundant eukaryotic noncoding RNA that assembles with protein cofactors to form the 7SK ribonucleoprotein (RNP), a dynamic complex that regulates transcription elongation. In particular, the 7SK RNA stem-loop 3 (SL3) domain is a critical hub for protein recruitment that is required for 7SK RNP function. We recently discovered that SL3 undergoes exchange between two equally populated yet structurally distinct conformers, named SL3e and SL3a, providing a model system to understand RNA conformational equilibria. Here, we combined quantitative dimethyl sulfate mutational profiling with sequencing (qDMS-MaPseq), solution NMR spectroscopy, and isothermal titration calorimetry (ITC) experiments to gain quantitative insights into SL3 equilibria under varying ionic conditions. We find that Mg
