Depression, anxiety and positive symptoms were significantly greater, and blood pressure (SBP, DBP), BMI, lipids (TC, TG, HDL, LDL), thyroid hormones (TSH, TgAb, TPOAb), and FBG were all higher in patients with FSA in the past 14 days than those who did not attempt suicide (p < 0.05). Here, TG is linked to major depressive disorder.
