Data were compared with all patients and with patients who did not fulfill any inclusion criteria. RESULTS: In total, 2,258 patients with SSc-ILD were included: 31.2% of the patients met SENSCIS criteria; 5.8% of the patients met SLS II criteria; 1.6% of the patients met focuSSced criteria, and 67.7% (1,529) of the patients did not meet any criteria. In the first 12 + 3 months, the absolute FVC decline in all patients and in patients who fulfilled criteria from SENSCIS was -0.1%, in patients who fulfilled criteria from focuSSced was -3.7%, and in patients who fulfilled criteria from SLS II was 2.3%, with accompanying more progressors in focuSSced.

Data were compared with all patients and with patients who did not fulfill any inclusion criteria. RESULTS: In total, 2,258 patients with SSc-ILD were included: 31.2% of the patients met SENSCIS criteria; 5.8% of the patients met SLS II criteria; 1.6% of the patients met focuSSced criteria, and 67.7% (1,529) of the patients did not meet any criteria.
