KLF11 and major depressive disorder: Significant differences in KLF11 DNA methylation were observed between MDD patients with and without anxious depression at CpG site 1 (p = 0.041) and, on a nominally significant level, with regard to average methylation (p = 0.052) and methylation at CpG sites 2–4 (p = 0.053-0.081; see Table 3; Fig. 3), with patients with non-anxious depression showing decreased KLF11 methylation.
