Linear correlation of SARP with nailfold videocapillaroscopy score and capillary diameter. Scatterplot of linear positive correlation of pulmonary artery systolic pressure with nailfold videocapillaroscopy score (a) and capillary diameter (b) in CTD-PAH patients, Univariate linear regression was used, R-values and regression equations were obtained. P < 0.05 was considered statistically significant. PASP pulmonary artery systolic pressure, CTD-PAH pulmonary arterial hypertension associated with connective tissue disease.
