Transport of Designed Ankyrin Repeat Proteins through reconstituted human bronchial epithelia and protection against SARS-CoV-2.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Clinical studies have proven antiviral effectiveness of treatment with a Designed Ankyrin Repeat Protein (DARPin) specific against the spike protein of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). More information on transport mechanisms and efficiency to the site of action is desirable. Transepithelial migration through air-liquid interface (ALI) cultures of reconstituted human bronchial epithelia (HBE) was assessed by Enzyme-Linked Immunosorbent Assays and Confocal Laser Scanning Microscopy for different DARPin designs in comparison to a monoclonal antibody. Antiviral efficacy against authentic SARS-CoV-2, applied apically on HBE, was investigated based on viral titers and genome equivalents, after administration of therapeutic candidates on the basal side. Transepithelial translocation of all DARPin candidates and the monoclonal antibody was efficient and dose dependent. Small DARPins and the antibody migrated more efficiently than larger molecules, indicating different transport mechanisms involved. Microscopic analyses support this, demonstrating passive paracellular transport of smaller DARPins and transcellular migration of the larger molecules. All therapeutic candidates applied to the basal side of HBE conferred effective protection against SARS-CoV-2 infection. In summary, we have shown that DARPins specific against SARS-CoV-2 translocate across intact airway epithelia and confer effective protection against infection and viral replication.
