From: Quantitative videocapillaroscopy correlates with functional respiratory parameters: a clue for vasculopathy as a pathogenic mechanism for lung injury in systemic sclerosis

  Cutolo’s pattern  
Normal (n = 15) Early (n = 23) Active (n = 59) Late (n = 37) p value
FVC, % predicted 89.1 (± 20.3) 82.3 (± 17.2) 85.3 (± 18.3) 69.6 (± 20.7)*,** 0.001
DLCO, % predicted 77.3 (± 20.8) 71.4 (± 27.5) 68.6 (± 20.4) 54.2 (± 23.3)*,†,‡ 0.002
