Respectively, the percentage of CD4+GranzB+CTLs in the pSS patients with arthritis (n = 5, 11.2% ± 4.6%), ILD (n = 17, 11.4% ± 4.9%), renal disease (n = 9, 10.5% ± 5.8%), purpura (n = 5, 15.5% ± 7.4%), PAH (n = 5, 13.5% ± 4.8%), autoimmune liver dysfunction (n = 3, 7.9% ± 2.5%), glandular swelling (n = 3, 9.5% ± 3.9%), hypocytosis (n = 29, 8.1% ± 4.1%), leukopenia (n = 15, 8.1% ± 4.1%), anemia (n = 7, 7.3% ± 3.8%), thrombocytopenia (n = 10, 7.0% ± 4.2%), and lymphopenia (n = 7, 9.1% ± 3.8%). Here, CD4 is linked to anemia (phenotype).
