Finally, we analyzed the ratio between Treg/Teff and found no differences in Tregs/CD4+ Teff ratio (0.072 (0.062; 0.089) vs. 0.069 (0.057; 0.075) with p > 0.05) and Tregs/CD8+ Teff ratio (0.137 (0.095; 0.191) vs. 0.133 (0.109; 0.188) with p > 0.05) between patients with sarcoidosis and the control group. Here, CD8A is linked to sarcoidosis.
