Basic correlations in the endometrium and correlation of endometrial HLA-F with anti-inflammatory macrophages. The figure shows plots of the whole cohort (n = 121). (A) HLA-F expression in the endometrial glands is positively correlated with HLA-F expression in the endometrial stroma. (B) CD56⁺ uNK cells are positively correlated with CD163⁺ anti-inflammatory macrophages. (Spearman’s correlation; p_c-values were adjusted by Bonferroni’s correction for multiple comparison). (C) The HLA-F expression in the endometrial stroma is positively correlated with the amount of anti-inflammatory M2 macrophages identified as CD163⁺ cells. (Spearman’s correlation; P_c-values were adjusted by Bonferroni’s correction for multiple comparison.).
