Methods: We conducted a meta-analysis following Cochrane methodology. Literature searches were performed up to May 1, 2024, using PubMed, Web of Science, Embase, The Cochrane Library, CNKI, VIP, and Wanfang databases. Studies assessing the diagnostic efficacy of miRNAs in VCI using sensitivity (Sen), specificity (Spe), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and summary receiver operating characteristic (SROC) were included. Subgroup analyses were conducted based on geographical regions and cognitive status. Results: Eight studies involving 1160 patients and examining 19 different types of miRNAs were included. The pooled sensitivity was 0.73 (95% CI 0.71~0.74), specificity was 0.77 (95% CI 0.75~0.79), positive likelihood ratio was 3.26 (95% CI 2.42~4.38), negative likelihood ratio was 0.33 (95% CI 0.26~0.43), diagnostic odds ratio was 10.64 (95% CI 6.42~17.61), and the SROC area under the curve was 0.83. Conclusion: This study demonstrates that miRNA profiles have high accuracy in diagnosing VCI and can serve as potential diagnostic biomarkers for VCI.展开更多
