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

The zona pellucida (ZP) domain is a bipartite protein structural element comprised of ZP-N and ZP-C regions. Most notable for its ability to mediate protein polymerization, many ZP proteins polymerize and assemble into long fibrils that form specialized extracellular matrices. Other ZP proteins (namely, betaglycan and endoglin) do not polymerize but serve as important membrane coreceptors for ligands in the transforming growth factor-β (TGF-β) superfamily. Here, we present the 2.0-Å resolution crystal structure of the betaglycan ZP-C region in combination with a downstream region known as the external hydrophobic patch (EHP). Similar to the ZP-N region, the ZP-C region also adopts an immunoglobulin-like fold, despite sharing no sequence homology and possessing different disulfide linkages. The EHP region, which was previously thought to be external to the ZP region, is integral to the ZP-C domain and corresponds to the ZP-C G strand. Our structure also indicates that the critical maturation cleavage of ZP proteins, a process that activates nascent ZP proteins for polymerization, occurs within the immunoglobulin domain at the FG loop. Nonpolymerizing ZP proteins such as betaglycan and endoglin do not contain this cleavage site. Finally, our structure suggests that the AB loop and the convex surface pocket are regions important for TGF-β ligand binding.
