  1. Spot quantity was assessed by PDQUEST 7.1 software on two BALF gel maps of individual SScFib+ (n = 9) and SScFib- (n = 6) patients. Spot quantity between SScFib+ and SScFib- patients did not differ significantly (Mann–Whitney U test, p > 0.05). Spot no. refers to the annotations in Figure 1. BALF, bronchoalveolar lavage fluid; 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; GM, gel matching with plasma two-dimensional gel electrophoresis database from Swiss-PROT [17] and published two-dimensional gel electrophoresis BALF maps [5,6]; Ab, immunoblotting.
