Objects and methods
• We designed this study to investigate the risk factors for progressive fibrosis in patients with RA-ILD. Factors including clinical, physiological, radiological and therapeutic variables were all included in the data analysis.
• Our results showed HRCT abnormalities, rather than other parameters, appeared predictive of progressive fibrosis in RA-ILD.
• The methods and results of image evaluation in this article would provide reference to rheumatologists in identifying early stage of progressive fibrosis which helps to improve poor prognosis of RA-ILD.
