PepString Server As a Tool to Search for Short Amino Acid Subsequences: Identification of Potential Amyloid-Beta Targets.
Article in Acta naturae. 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
This paper presents a new bioinformatics tool to meet the needs of researchers in the search for short (≥ 3) amino acid subsequences in protein sequences annotated in public databases (UniprotKB, SwissProt) and illustrates its efficacy with the example of a search for the EVHH tetrapeptide in the human proteome, which is a molecular determinant of amyloid beta and is involved in interactions that are crucial in Alzheimer's disease pathogenesis. The topicality of developing such a tool is, on the one hand, supported by experimental data on the role of short tetrapeptide motifs in the architecture of intermolecular interfaces. On the other hand, there are currently no software products for efficient search for short (≥3) amino acid sequences in public databases, which drastically limits researchers' ability to identify proteins with exact matches of short subsequences. This tool (PepString server, http://pepstring.eimb.ru/) allows one to use intuitive queries to retrieve information about all the proteins that contain sequences of interest, as well as their combinations.
