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

This paper reports a method for fabricating multilayer microfluidic protein crystallization platforms using different materials to achieve X-ray transparency and compatibility with crystallization reagents. To validate this approach, three soluble proteins, lysozyme, thaumatin, and ribonuclease A were crystallized on-chip, followed by on-chip diffraction data collection. We also report a chip with an array of wells for screening different conditions that consume a minimal amount of protein solution as compared to traditional screening methods. A large number of high quality isomorphous protein crystals can be grown in the wells, after which slices of X-ray data can be collected from many crystals still residing within the wells. Complete protein structures can be obtained by merging these slices of data followed by further processing with crystallography software. This approach of using an x-ray transparent chip for screening, crystal growth, and X-ray data collection enables room temperature data collection from many crystals mounted in parallel, which thus eliminates crystal handling and minimizes radiation damage to the crystals.
