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

Granular mixing, ubiquitous in industry, is difficult to observe. Ultrafast X-ray computed tomography is a relatively new technique that can be used to study rapid granular flows in opaque systems. A comparative study is here presented, where ultrafast X-ray computed tomography, camera and simulation with the Discrete Element Method are simultaneously used to investigate the radial segregation of 4-mm spherical polypropylene and glass beads in a rotating drum. The drum filling is varied from 20 to 50%. The granular flow and the associated segregation dynamics at the front-end wall and in the bulk are compared and good agreement among the three methods is found. Similar to unary systems, a transition from the rolling to the sliding regime, characterized by a critical dynamic angle of repose, is also reported.
