Quantitative Analysis of Composite Polymeric Membrane Structure Using Contour Morphological Heterogeneity Functions.
Article in Polymers, 2026. 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
We have developed a quantitative method for characterizing the actual multilayer polymer material-made membranes' architecture with a computer analysis of their scanning electron microscopy (SEM) images. The proposed approach consists of contour morphological heterogeneity function (CMHF) calculations. The approbation was carried out on polysulfone, polytetrafluoroethylene and polyimide-made membranes. The corresponding CMHF series were computed for different depths. It was possible to identify the structural zones' location for all the considered membranes. The developed technique provides the possibility of standardizing the SEM images' analysis and determining the thicknesses of the surface, transition and volumetric layers of filtering and separating equipment elements. The suggested algorithm can automate the membrane's structure and architecture metrological analysis with computer vision techniques.
