Age*, age at diagnosis of RA; Age**, age at diagnosis of ILD. (All the other parameters represent the baseline values). DAS28-ESR, Disease Activity Score-28; FVC, forced vital capacity; DLCO, diffusing capacity of carbon monoxide; anti-RF, anti- Rheumatoid factor; anti-CCP, anti-cyclic citrullinated peptide
