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

Overcoming line broadening of labile protons and achieving high-resolution NMR spectra is crucial for the structural and conformational analysis of organic molecules. Recently, Ma et al. (Magn. Reson. Chem. 2024, 62, 198-207) demonstrated the effectiveness of 2,2,2-trifluoroacetic acid (TFA) in sharpening NMR signals for nitrogen-containing compounds which exhibit prototropic tautomerization or conformational isomerism using high molar ratio of [acids]/[solute] ~ 5 to 200. In this commentary, we provide an overview of earlier publications and highlight the extensive applications of TFA in enhancing NMR resolution across a variety of organic functional groups, with the use of very small ratios of [acids]/[solute] ~ 10
