  1. Results are given as mean ± SD. SScFib+, systemic sclerosis patients with functional lung fibrosis and signs of lung fibrosis on high-resolution computed tomography; SScFib-, SSc patients with no signs and symptoms of lung fibrosis. Control values are taken from data previously assessed in a group of healthy volunteers [12]. BAL, bronchoalveolar lavage; ND, not determined. ap < 0.05 compared with controls (all assessed by Student's t test).
