  1. Differences in nailfold videocapillaroscopy score between CTD-PAH, CTD-non-PAH and non-CTD healthy people were analyzed by Student’s t-test, and score were expressed as mean ± standard deviation, with P < 0.05 considered statistically different, CTD-PAH pulmonary arterial hypertension associated with connective tissue disease, CTD-non-PAH connective tissue disease not complicated with pulmonary arterial hypertension.
  2. * P1 value refers to differences between CTD-PAH and CTD-non-PAH. ** P2 value refers to differences among CTD-PAH, CTD-non-PAH and non-CTD healthy people.
