Figure 1.
An example of high–resolution CT images.
Analysis of each finding was as follows. Honeycombing: negative; Bronchiectasis: positive; Dilatation of pulmonary artery: negative; Extent of ground glass attenuation: grade 1; Extent of consolidation: grade 1; Extent of reticular abnormality: grade 2; Extent of micronodules: grade 2. This case was diagnosed as fibrotic nonspecific interstitial pneumonia pattern. (a) at the aortic arch. (b) at the carina tracheae. (c) at the right pulmonary vein. (d) at the top of the right diaphragm.

Examples of pathological scoring (hematoxylin–eosin, × 100).
Typical images in each grade of fibroblastic foci (straight arrows) [(a): grade 1 and (b): grade 3] and bronchiolar fibrosis [(c): grade 1 and (d): grade 3] were listed.

Kaplan–Meier survival curves for patients with interstitial lung disease associated with primary Sjögren’s syndrome.
(a) Survival curve for the total patient population. Five-year survival rate was 87.3%. (b) Comparison of survival curves between the NSIP (n = 22) and UIP (n = 11) patients. Open circles or open squares show censored cases in NSIP group or UIP group, respectively. The prognosis between the two groups was not significantly different (P = 0.93 in log–rank test). UIP: usual interstitial pneumonia; NSIP: nonspecific interstitial pneumonia.
