Analysis of erythrocyte deformation characteristics based on dual-angle Mueller matrix measurement.
Article in Frontiers of optoelectronics, 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 vital components of human blood, and their morphological abnormalities serve as reliable indicators of various disease pathophysiologies. As a novel label-free optical technique, Mueller matrix (MM) polarimetry is gaining recognition for its value in disease diagnosis and pathological analysis. In this study, we integrate a dual-angle MM measurement system with single-cell polarized light scattering modeling to establish specific polarization feature parameters (PFPs) characterizing cellular microphysical properties. The PFPs quantitatively describe morphological and optical changes in individual RBCs undergoing complex deformations. Experimental results demonstrate that PFPs can effectively distinguish differences in size, shape, refractive index, and surface spicules between deformed and normal RBCs. Moreover, by incorporating PFPs into a Random Forest classifier, we accurately quantify the proportion of abnormal RBCs in mixed suspensions. This study confirms the capability of polarization measurement for label-free, high-throughput analysis of RBC microphysical properties at the single-cell level.
