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

Photo chemically induced dynamic nuclear polarization (photo-CIDNP) and long-lived spin states (LLS) are two nuclear magnetic resonance (NMR) techniques that can be combined to achieve large signal enhancements and extended lifetimes of spin order, respectively, and their combination is useful for detecting biomolecular interactions. Here, we demonstrate that integrating photo-CIDNP hyperpolarization with LLS excitation through spin-lock induced crossing (SLIC) enables the highly sensitive detection of signals of ligands at micromolar concentrations. Using indole-3-propionic acid (IPA), we show that two of its CH
