Affinity Purification of Glycosylphosphatidylinositol-anchored Proteins by Alpha-Toxin.
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
The glycosylphosphatidylinositol (GPI)-anchor modification attaches a lipid anchor to the C-terminus of a protein, tethering the protein to the cell surface membrane. From this membrane-bound state, GPI-anchored proteins (GPI-APs) can be released into the extracellular space by multiple mechanisms, including proteolytic shedding and GPI lipase activity. Since the core GPI structure is co-released with the protein by GPI lipase activity, while removed from the protein by proteolytic cleavage, affinity purification by alpha-toxin (αToxin), which binds to the core domain of the GPI-anchor, isolates GPI-containing proteins from the culture medium. The following method details a technique for affinity purification of GP-APs using His-tagged αToxin for identification of GPI-anchored proteins, analysis of the GPI-anchor status of a protein of interest, or purification for subsequent biochemical analysis.
