Objective To compare the difference in incidence of sexual dysfunction induced by mirtazapine and venlafaxine in treating patients with depression.Methods A total of 12 published clinical control trials on depression treated by mirtazapine and venlafaxine were analyzed by applying fixed effects model(FEM) of evidence-based medicine(EBM).Results A total of 313 cases in 5 studies were included,and the rates of sexual dysfunction induced by mirtazapine,and venlafaxine were 0.63% and 9.74%(Z=2.96,P0.01),comprehensive OR was 0.10,and 95% CI was from 0.06 to 0.56.Conclusion Compared with mirtazapine,more attention should be paid to venlafaxine for inducing sexual dysfunction when treating depression.
