Use of Protein Thin Film Organized by External Electric Field as a Template for Protein Crystallization.
Article in ACS omega, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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 well-known difficulty to obtain high-quality protein crystals has motivated researchers to come up with new methods or modifications of established crystallization methods to stimulate the growth of good diffracting crystals. In the present work, a new approach, using a protein thin film organized by external electric field (EEF) as a template for protein crystal growth, is introduced. This method increased nucleation of hen egg white lysozyme (HEWL) in comparison with the classical vapor diffusion method, besides improving crystal morphology and size. X-ray diffraction analyses indicated improvements in crystal quality. When HEWL was crystallized at pH 6.2, in which this protein presents biological activity, the control crystal presented a poorly ordered crystalline structure and a low resolution cutoff at 3.42 Å, whereas the crystal grown with the EEF protein film revealed a high-resolution limit at 1.67 Å. These results suggest that protein films organized by EEF may improve protein crystals and their data quality.
