A meta-analysis was conducted to summarize the evidence from randomized controlled trials （RCT） which investigated potential impact of THI on the incidence of CVD in patients with or without prior CVD. Methods PubMed, EmBase, and the Cochrane Library were searched to identify RCTs to fit our analysis through December 2016. Relative risk （RR） with its 95% confidence interval （CI） was used to measure the effect of THI using a random-effect model. Sensitivity analysis, subgroup analysis, heterogeneity tests, and tests for publication bias were also conducted. Results Eight RCTs were included and with a total of 1635 individuals. The summarized results indicated that participants who received THI showed a significant reduction of the CVD incidence as compared with usual care （RR： 0.59; 95% CI： 0.47-0.74; P 〈 0.001）. Furthermore, the effect of THI was greater in patients with history ofCVD （RR： 0.55; 95% CI： 0.44-0.70; P 〈 0.001） than in patients without history ofCVD （RR： 0.99; 95% CI： 0.51-1.94; P = 0.977）. Sensitivity analysis suggested that the intervention effect persisted and the conclusion was not changed. Subgroup analysis indi- cated mean age, study quality might play an important role on the risk of CVD. Conclusions The findings of this study indicated THI could reduce the recurrence of CVD. Further large-scale trials are needed to verify the effect of THI on CVD in healthy individuals.展开更多
