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

Creating stabilized peptide mimics of the collagen triple helix is challenging, especially for collagen heterotrimers. Interstrand sidechain crosslinking offers a useful approach, though this strategy can suffer from destabilizing structural perturbations, sequence limitations and synthetic complexity. Herein, we show that the geometry of hydrogen bonding in the collagen triple helix is compatible with installation of terminal β-turn-mimicking linkers at the N-terminal and C-terminal ends of the triple helix. These double-turn-containing collagen peptide mimics fold into highly stable, intramolecular triple helical structures, providing access to profoundly miniaturized triple helix mimics. Intramolecular triple helix formation exhibits significantly accelerated folding kinetics. Comprehensive kinetic analysis reveals that the rate-limiting step of folding is distinct at low and high temperatures, affording unique insight into the mechanism.
