borderline significancep = .06
Comparing frequencies of different NK cell subsets, the results revealed a borderline significance in the lower percentage of conventional cytotoxic NK cells with CD3 − CD56 dim CD16 + phenotype (9.88 ± 1.30 vs. 12.44 ± 1.49, p = .06) and a higher percentage of tolerant NK cells with CD3 − CD56 + CD27 − CD11b − phenotype (0.82 ± 0.13, 0.48 ± 0.10, p = .06) in peripheral blood of the patients compared to the HDs.
