Surface-attached model lipid membranes derived from human red blood cells.
Article in bioRxiv : the preprint server for biology, 2025. 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
Red blood cells (RBCs) are the most abundant human cell type and interface interactions with the RBC membrane are at the heart of many processes relevant for human health, such as immune system modulation, interactions with foreign pathogens and with pharmacological drugs. To better study such membrane interface interactions, it would be useful to employ surface-attached model lipid membranes derived from RBCs to enable surface-sensitive biophysical and biochemical measurements. Here, we present approaches to prepare two such types of RBC-derived model lipid membranes - supported lipid bilayers (RBC-SLBs) and tethered RBC liposomes. We present data characterizing and validating these model membranes, including assessing lipid mobility, the distribution and mobility of the glycophorin A membrane protein, the functionality of the acetylcholinesterase enzyme, and the utility of the RBC-SLBs as binding targets for viral pathogens. We anticipate that our results and methodologies will be of interest to researchers studying molecular interactions with RBC membranes, as well as those interested in the engineering of model membrane platforms derived from other physiological membranes.
