Modular Nanotransporters Capable of Binding to SARS-CoV-2 Virus Nucleocapsid Protein in Target Cells.
Article in Doklady. Biochemistry and biophysics, 2023. 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
On the basis of literature data, an antibody-like molecule, monobody, was selected that is capable of interacting with the nucleocapsid protein (N protein) of the SARS-CoV-2 virus with a high affinity (dissociation constant 6.7 nM). We have previously developed modular nanotransporters (MNTs) to deliver various molecules to a selected compartment of target cells. In this work, a monobody to the N protein of the SARS-CoV-2 virus was inserted in the MNT using genetic engineering methods. In this MNT, a site for the cleavage of the monobody from the MNT in endosomes was also inserted. It was shown by thermophoresis that the cleavage of this monobody from the MNT by the endosomal protease cathepsin B leads to a 12-fold increase in the affinity of the monobody for the N protein. Cellular thermal shift assay showed the ability of the obtained MNT to interact with the N protein in A431 cells transfected with the SARS-CoV-2 N protein fused to the mRuby3 fluorescent protein.
