Fifty patients (96%) had skin sclerosis, 39 (75%) had diffuse skin involvement with a median modified Rodnan skin score of 14 (0\u201338). Thirty-eight (76%) had interstitial lung disease, with median forced vital capacity and diffusing lung capacity for carbon monoxide of 81% (37\u2013127) and 56% (28\u2013103) from predicted values, respectively. Twenty-five (51%) patients had pulmonary fibrosis. Mycophenolate mofetil was given for 10\u2009months (0\u2013173) at a median dose of 2000\u2009mg\/day (500\u20133000).
