Fig. 2From: Circulating Th2 cell reduction and Th1/Th2 imbalance are correlated with primary Sjogren’s syndrome-associated interstitial lung diseaseComparison of the absolute numbers of circulating CD4+ T subsets among HCs, pSS-non-ILD patients, and pSS-ILD patients. Th, helper T; Treg, regulatory T; 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. Significance values are asymptotic (2-sided tests), and the significance level was P < 0.05Back to article page
