CD8A and sarcoidosis: On the other hand, when sarcoidosis was established as the dependent variable, the percentages of BALF NK and CD8+ cells were significantly associated with a lower risk of having a diagnosis of sarcoidosis: adjusted OR = 0.851 per each 1% increase in the percentage of NK cells (95%CI = 0.753–0.963; p = 0.010); and adjusted OR = 0.949 per each 1% increase in the percentage of CD8+ cells (95%CI = 0.932–0.966; p < 0.001) (Table 3C).
