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

In the accompanying paper, we found, using molecular dynamics calculations, four domains of the ras-specific SOS guanine nucleotide exchange protein (residues 589-601, 654-675, 746-761, and 980-989) that differ markedly in conformation when SOS is complexed with either oncogenic (Val 12-) ras-p21 or wild-type ras-p21. Three of these domains contain three crystallographically undefined loops that we modeled in these calculations, and one is a newly identified non-loop domain containing SOS residues 980-989. We have now synthesized peptides corresponding to these four domains and find that all of them block Val 12-ras-p21-induced oocyte maturation. All of them also block insulin-induced oocyte maturation, but two of these peptides, corresponding to SOS residues 589-601 and 980-989, block oncogenic ras to a significantly greater extent. These results suggest that SOS contains domains, including the three loop domains, that are important for ras signaling and that several of these domains can activate different pathways specific to oncogenic or wild-type ras-p21.
