Expressed protein ligation-mediated template protein extension.
Article in Protein expression and purification, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Expressed protein ligation (EPL) was performed to investigate sequence requirements for a variant human apolipoprotein A-I (apoA-I) to adopt a folded structure. A C-terminal truncated apoA-I, corresponding to residues 1-172, was expressed and isolated from Escherichia coli. Compared to full length apoA-I (243 amino acids), apoA-I(1-172) displayed less α-helix secondary structure and lower stability in solution. To determine if extension of this polypeptide would confer secondary structure content and/or stability, 20 residues were added to the C-terminus of apoA-I(1-172) by EPL, creating apoA-I(Milano)(1-192). The EPL product displayed biophysical properties similar to full-length apoA-I(Milano). The results provide a general protein engineering strategy to modify the length of a recombinant template polypeptide using synthetic peptides as well as a convenient, cost effective way to investigate the structure/function relations in apolipoprotein fragments or domains of different size.
