As illustrated in Figure 3B, compared to the CG, AERE (MD = 3.36, 95% credible interval [CrI] [1.11, 5.64]), RE (MD = 3.22, 95% CrI [0.71, 5.76]), and yoga (MD = 3.04, 95% CrI [0.61, 5.43]) were all associated with significant increases in BDNF levels among patients with depression. Here, BDNF is linked to major depressive disorder.
