Correlation and receiver operating characteristic (ROC) analysis about results of intravital capillaroscopy and OCTA. A Scatter plots of correlation between RCD and SCD (a) and scatter plots of correlation between R-NPA and SCD (b). B ROC curve for SCD and RCD, R-NPA. ROC was performed for blood pressure (definition of high blood pressure), n = 140. a with SBP analysis, AUC for SCD is 0.68, 0.72 for RCD and 0.79 for R-NPA; b with DBP analysis, AUC for SCD is 0.64, 0.81 for RCD and 0.78 for R-NPA. OCTA optical coherence tomography angiography, SCD skin capillary density, RCD retina capillary density, R-NPA retina non-perfused areas, AUC area under the curve
