Participant distributions and characteristics in Chinese men with type 2 diabetes according to the European classification. (a) Distributions of Chinese men (n = 3087) according to the two‐step cluster analysis. (b) Distributions of age at diagnosis for each cluster. (c) Distributions of body mass index (BMI) for each cluster. (d) Distributions of glycosylated hemoglobin (HbA₁c) for each cluster. (e) Distributions of homeostatic model assessment 2 to estimate β‐cell function (HOMA2‐B) for each cluster. (f) Distributions of homeostatic model assessment 2 to estimate insulin resistance (HOMA2‐IR) for each cluster. HOMA2‐B and HOMA2‐IR were applied to estimate the function of β‐cell and insulin resistance, respectively, which were calculated using fasting plasma glucose and c‐peptide. BMI was calculated as weight (kg) / height (m²). MARD, mild age‐related diabetes; SAID, severe autoimmune diabetes; SIDD, severe insulin‐deficient diabetes.
