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

Ribonuclease A (RNase A) undergoes more rapid conformational folding with its disulfide bonds intact than during oxidative folding from its reduced form. In this study, the effects of the mutants Y92G, Y92A, and Y92L on both the conformational and oxidative folding pathways were examined to determine the role of native interactions in different types of conformational searches for the biologically active structure of a protein. These mutations did not affect the overall conformational folding pathway of RNase A. However, in the mutants Y92G and Y92A, a key structured disulfide-bonded species, des-[65-72], involved in the oxidative folding pathway of RNase A, was destabilized. These results demonstrate the importance of native interactions in the folding process, namely, protection of a native (40-95) disulfide bond by a nearby tyrosyl-prolyl stacking interaction, when disulfide bonds are allowed to undergo SH/S-S reshuffling.
