A simple staging system for prediction of survival in patients with SSc-ILD. a Patients with SSc may be classified as having limited disease or extensive disease based on the extent of fibrosis seen on HRCT of the lungs, plus FVC per cent predicted in patients with 10–30% fibrosis on HRCT. b Extensive lung disease is a significant predictor of mortality with a hazard ratio of 3.46 compared to limited disease [30].
