  • Disease progression and/or treatment response for patients with ASyS at around 1 year was defined on lung function as a decrease or increase in FVC by more or less than 10% predicted (respectively) compared with baseline, and/or decrease or increase in TLCO by more or less than 15% predicted (respectively), as used in systemic sclerosis.10

  • ASyS, antisynthetase syndrome; FVC, forced vital capacity; ILD, interstitial lung disease; TLCO, transfer factor for carbon monoxide.
