  • All patients had diffuse cutaneous SSc. The disease subset was determined according to the criteria proposed by LeRoy et al.19 Disease duration was measured from the onset of the first non-Raynaud symptoms attributable to SSc. Pulmonary arterial hypertension was diagnosed by right heart catheterisation. Disease activity was determined using the EULAR Systemic Sclerosis Activity Score. Patients with scores of ≥3 were classified as having active disease.

  • DMARD, disease-modifying antirheumatic drug; F, female; M, male; NSAID, non-steroidal anti-inflammatory drug.
