Fig. 1From: Circulating Th2 cell reduction and Th1/Th2 imbalance are correlated with primary Sjogren’s syndrome-associated interstitial lung diseaseComparison of the absolute numbers of peripheral lymphocyte subsets among HCs, pSS-non-ILD patients, and pSS-ILD patients. NK, natural killer; HCs, healthy controls; pSS, primary Sjogren’s syndrome; ILD, interstitial lung disease; pSS-non-ILD, pSS without ILD; pSS-ILD, pSS with ILD. *P < 0.05, **P < 0.01, ***P < 0.001. P (2-sided tests) < 0.05 was considered statistically significantBack to article page
