Intrinsically Disordered Proteins (IDP): Purification Under Denaturing Conditions.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Recombinant protein expression in E. coli often induces the expressed protein to accumulate in insoluble aggregates, named inclusion bodies (IBs), that represent easy to isolate, highly pure protein reservoirs. IBs can be solubilized by denaturing agents but this procedure requires, for complex globular proteins, a refolding step that can be challenging. However, the lack of cooperatively folded tertiary structure in intrinsically disordered proteins (IDP) makes them ideal candidates for this purification strategy. Given the wide abundance of IDPs, their relevance in many disease areas and the numerous IDP-associated biological functions, the interest in this class of proteins has increased substantially over the last decade. Here we present a broad and versatile method for the production and isolation of IDPs from inclusion bodies under denaturant conditions that overcomes the challenges associated with the propensity of these sequences to precipitate from solution and becoming proteolytically degraded.
