Changes in HRCT variables in patients with pSS-ILD before and after treatment. Plots are shown for the total extent (A) ground-glass opacities (GGO) (B), fine reticulation (C), coarse reticulations (D), coarseness score of fibrosis (E), and score of traction bronchiectasis (BE). Blank triangles and dotted lines indicate pSS-ILD patients without progression, and filled circles and solid lines represent patients with progression. *p-value < 0.05, **p-value < 0.01, based on the Wilcoxon signed-rank test, Red asterisk: compared to baseline CT, Blue asterisk: compared to before immunosupressants (IS).
