Evaluation of GRADE evidence quality.

Outcome indicators	95% CI	Risk of bias	Inconsistency	Indirectness	Imprecision	Publication bias	Upgrade quality of evidence	Quality
HAMA post treatment score reduction	RR 1.03 (0.95, 1.12)	serious①	No	No	No	Undetected	None	Moderate
HAMD post treatment score reduction	RR 1.05 (0.99, 1.10)	serious①	serious②	No	No	Undetected	None	Low
Efficacy of TCM	RR 1.19 (1.13, 1.25)	serious①	No	No	No	Undetected	None	Moderate
SAQ	SMD 0.58 (0.33, 0.84)	serious①	serious②	No	No	Undetected	None	Low
Incidence of adverse reactions	RR 0.54 (0.43, 0.68)	serious①	No	No	No	Undetected	None	Moderate

SMD is the standardized mean difference; RR is the relative risk; ① absence of allocation concealment and blinding; ② the value of the heterogeneity test was <0.1, and I² >50%.
