Abstract:Objective To systemically investigate the efficacy of integrated traditional Chinese and Western Medicine on transient ischemic attack. Methods We searched the Chinese National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform (WDKSP) and Chinese Scientific Journals Full-Text Database from Jul 1, 1990 to Jul 1, 2018 for Chinese database; Cochrane library, PubMed, springer link, EBSCO-Academic Search Complete, Elsevier-SDOL (ScienceDirect Online) from inception to Jul 1, 2018 for English database. Randomized controlled trails and semi-randomized controlled trails were included in this study. The odds ratio (OlR) and standardized mean difference (SMD) were used to evaluate the effect of integrated traditional Chinese and Western Medicine on transient ischemic attack. The extracted data were analyzed by Review Manager 5.3. Results Totally 20 studies including 1794 patients were involved to evaluate the efficacy of integrated traditional Chinese and Western Medicine on transient ischemic attack. The OlR value was 4.36 (95% CI: 3.16, 6.00, P?0.05) and the SMD was -0.13 (95% CI: -0.22, 0.05, P?0.05). Conclusions Integrated traditional Chinese and Western Medicine reduce the frequency of transient ischemic attack, which may potentially be a therapeutic option.
