Although the CC genotype of rs2910164 significantly increased the risk of MI under dominant and additive models (P < 0.05), this difference disappeared after adjustment for age, sex, blood pressure, triglycerides, total cholesterol, HDL, LDL and diabetes.
The miR-146a rs2910164 polymorphism might be associated with carotid vulnerable plaque risk in Chinese type 2 diabetes mellitus patients, particularly in older patients, females, those with diabetes duration of more than 10 years and those with hypertension.
In conclusion, this meta-analysis indicated that miRNA27a rs895819 might play a protective role in diabetes, and miRNA146a rs2910164 likely had no association with diabetes.
