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

Terminal deletions of units from alpha-helical repeat proteins have provided insight into the physical origins of their cooperativity. To test if the same principles governing cooperativity apply to beta-sheet-containing repeat proteins, we have created a series of C-terminal deletion constructs from a large leucine-rich repeat (LRR) protein, YopM. We have examined the structure and stability of the resulting deletion constructs by a combination of solution spectroscopy, equilibrium denaturation studies, and limited proteolysis. Surprisingly, a high degree of nonuniformity was found in the stability distribution of YopM. Unlike previously studied repeat proteins, we identified several key LRR that on deletion disrupt nearby structure, at distances as far away as up to three repeats, in YopM. This partial unfolding model is supported by limited proteolysis studies and by point substitution in repeats predicted to be disordered as a result of deletion of adjacent repeats. We show that key internal- and terminal-caps must be present to maintain the structural integrity in adjacent regions (roughly four LRRs long) of decreased stability. The finding that full-length YopM maintains a high level of cooperativity in equilibrium unfolding underscores the importance of interfacial interactions in stabilizing locally unstable regions of structure.
