Cohort study 

研究目的:

1. 主要目的: (1) 评估G6PD基因突变与心脑血管并发症(复合终点)的关联。 (2) 量化G6PD基因突变对2型糖尿病患者HbA1c水平的低估效应。 2. 次要目的: (1) 验证HbA1c低估是否在G6PD突变与心脑血管并发症之间起中介作用。 (2) 建立适合G6PD突变患者的HbA1c校正公式及糖化白蛋白(GA)监测方案。 (3) 评估治疗误分类率(HbA1c<7.0%但GA>20%)。  

Objectives of Study:

Primary Objectives: 1. To assess the association between G6PD gene mutations and cardiocerebrovascular complications (composite endpoint). 2. To quantify the underestimation effect of G6PD gene mutations on HbA1c levels in patients with type 2 diabetes mellitus. Secondary Objectives: 1. To verify whether HbA1c underestimation plays a mediating role between G6PD mutations and cardiocerebrovascular complications. 2. To establish an HbA1c correction formula and a glycated albumin (GA) monitoring strategy suitable for patients with G6PD mutations. 3. To evaluate the treatment misclassification rate (HbA1c < 7.0% with GA > 20%).
