CALR and interstitial lung disease: Multivariate analysis confirmed that dyspnea at IIM onset as well as anti-52 kD Ro antibodies predict the development of ILD (p: 0.0155 and p: 0.0026, respectively), while facial rash and anti-NXP-2 antibodies were associated with no ILD development during follow-up (p: 0.055 and p: 0.0003, respectively).
