Subgroup analyses for the effect of fish oil supplementation on flow-mediated dilation according to predefined study characteristics.

FMD, flow-mediated dilation; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; TG, triglyceride; TC, total cholesterol; ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker; DHA, docosahexaenoic acid; EPA, eicosapentaenoic acid; R, randomized; DB, double-blinded; PC, placebo-controlled; WMD, weighed mean difference; CI, confidence interval.FMD：血流介导的血管扩张（flow-mediated dilation）；BMI：体重指数（body mass index）；SBP：收缩压（systolic blood pressure）；DBP：舒张压（diastolic blood pressure）；TG：甘油三酯（triglyceride）；TC：总胆固醇（total cholesterol）；ACEI：血管紧张素转换酶抑制剂（angiotensin-converting enzyme inhibitor）；ARB：血管紧张素受体阻滞剂（angiotensin receptor blocker）；DHA：二十二碳六烯酸（docosahexaenoic acid）；EPA：二十碳五烯酸（eicosapentaenoic acid）；R：随机（randomized）；DB：双盲（double-blinded）；PC：安慰剂对照（placebo-controlled）；WMD：加权均数差（weighed mean difference）；CI：置信区间（confidence interval）
