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

A new pulse sequence exploiting double- and zero-quantum evolution of two-spin 15N-13C' coherence is proposed for the accurate measurements of 2J(N(i),C alpha(i-1)) coupling constants. Application of the new experiment is presented for 13C,15N-labeled ubiquitin sample. The density functional theory calculations of 2J(N(i),C alpha(i-1)) coupling constants have been performed to study their dependence on both psi(i - 1) and phi(i - 1) angle in model peptides, and the results exhibit a good correlation with experimental data.
