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

Two crystal structures are described for the lysosomal aspartic protease cathepsin D (EC 3.4.23.5). The molecular replacement method was used with X-ray diffraction data to 3 A resolution to produce structures for human spleen cathepsin D and for bovine liver cathepsin D complexed with the 6-peptide inhibitor pepstatin A. The lysosomal targeting region of cathepsin D defined by previous expression studies [Barnaski et al. (1990) Cell, 63, 281-219] is located in well defined electron density on the surface of the molecules. This region includes the putative binding site of the cis-Golgi phosphotransferase which is responsible for the initial sorting step for soluble proteins destined for lysosomes by phosphorylating the carbohydrates on these molecules. Carbohydrate density is visible at both expected positions on the cathepsin D molecules and, at the best defined position, four sugar residues extend towards the lysosomal targeting region. The active site of the protease and the active site cleft substrate binding subsites are described using the pepstatin inhibited structure. The model geometry for human cathepsin D has rms deviations from ideal of bonds and angles of 0.013 A and 3.2 degrees respectively. For bovine cathepsin D the corresponding figures are 0.014 A and 3.3 degrees. The crystallographic residuals (R factors) are 16.1% and 15.8% for the human and inhibited bovine cathepsin D models respectively. The free R factors, calculated with 10% of the data reserved for testing the models and not used for refinement, are 25.1% and 24.1% respectively.
