Meta-analysis of the epidemiology of microvascular complications in people with Type 2 diabetes in mainland China

Abstract

Objective: This study aims to estimate the overall prevalence of microvascular complications of type 2 diabetes in mainland China, and to identify any associated risk factors. Methods: A systematic literature search was conducted to collect the prevalence information of microvascular complications over the past 5 years (2014 -2019) in CNKI, Wanfang, PubMed and the Cochrane Library. A meta-analysis was conducted using R3.4.3 following normal transformations given the skewed raw data. Due to high heterogeneity, a random effect model was selected. A meta-regression analysis was performed to investigate risk factors.
