EDN1 and angina pectoris: NMA results showed that SXBX had the highest probability of being the best treatment on account of the reduction of IMR [MD = −5.93, 95% CI (−8.75, −3.11)] and LDL-C [[MD = −0.56, 95% CI (−0.99, −0.14)], XB showed better efficacy in improving CFR [MD = 0.71, 95% CI (0.53, 0.89)], TXL showed better efficacy in angina attack frequency [MD = −5.30, 95% CI (−7.08, −3.53)]; YXTL showed better efficacy in hs-CRP [MD = −5.04, 95% CI (−8.38, −1.7)]; XKS showed better efficacy in ET-1 [MD = −43.3, 95% CI (−59.71, −26.89)]; YDXNT showed better efficacy in NO [MD = 17.69, 95% CI (6.07, 29.32)].
