CRP and major depressive disorder: In fully adjusted models (Model 2), each one-unit increase in the MIND score correlated with lower depression (HADS-D β = −1.23, 95% CI: −1.36 to −1.10) and anxiety (HADS-A β = −1.23, 95% CI: −1.36 to −1.10) scores, better sleep quality (PSQI β = −0.62, 95% CI: −0.69 to −0.55), decreased inflammatory markers CRP (β = −0.56, 95% CI: −0.61 to −0.52) and IL-6 (β = −0.79, 95% CI: −0.84 to −0.74).
