Higher percentage of CD4+GranzB+CTLs in pSS patients with extra-gland manifestations (extra-GM). A The frequency of CD4+GranzB+CTLs in pSS patients with non-extra-gland manifestations (non-extra-GM) (n = 55) and with extra-GM (n = 61). B The percentage of CD4+GranzB+CTLs in pSS patients with different number of extra-GM (non-extra-GM group n = 55, one extra-GM group n = 45, more than one extra-GM group n = 16). C Comparisons of the pSS patients with non-extra-GM, the percentage of CD4+GranzB+CTLs in pSS patients with different types of extra-GM (non-extra-GM group n = 55, hypocytosis group n = 29, ILD group n = 17, renal disease group n = 9, arthritis group n = 5, purpura group n = 5, PAH group n = 5, liver dysfunction group n = 3, glandular swelling group n = 3). D Comparisons of the pSS patients with non-extra-GM, the percentage of CD4+GranzB+CTLs in pSS patients with different types of various hypocytosis (non-extra-GM group n = 55; anemia group n = 7; leukopenia group n = 15; thrombocytopenia group n = 10; lymphopenia group n = 7). ***p < 0.001, **p < 0.01, *p < 0.05. ns, no significance
