随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用前瞻性非随机对照设计,按照年龄(±5 岁)、性别和体重指数(BMI)类别进行 1:1 个体匹配,以确保糖尿病组与非糖尿病对照组在关键基线特征上的可比性,从而减少潜在混杂因素的影响。匹配后通过计算标准化差(standardized mean difference, SMD)评估基线平衡性 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This was a prospective, non-randomized controlled study with 1:1 individual matching based on age (+/-5 years), sex, and body mass index (BMI) categories. Matching was performed to ensure comparability between patients with and without type 2 diabetes and to minimize potential confounding. Baseline balance after matching was assessed using standardized mean differences (SMD) |
