Unraveling structural transitions and kinetics along the fold-switching pathway of the RfaH C-terminal domain using exchange-based NMR.

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.
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 bacterial transcriptional regulator RfaH comprises structurally and functionally distinct N- (NTD) and C- (CTD) terminal domains. The latter switches from a helical hairpin packed against the NTD to a five-stranded β-roll upon displacement by RNA polymerase binding. Here, we use exchange-based NMR to probe fold-switching intermediates sampled by the isolated CTD. In addition to the predominant (~76 to 77%), semistable β-roll conformation (state A), we identify four structurally and kinetically distinct states: A', B, B', and B″. State B is NMR observable with an occupancy of ~23%, exchanges slowly (τ
