Prevalence and clinical characteristics of diabetic retinopathy in patients newly diagnosed with ketosis-onset diabetes: A real-world study

Figure 3 Comparison of islet function-related parameters. A: Comparison of serum fasting C-peptide levels among patients with type 1 diabetes mellitus (T1DM), ketosis-onset diabetes and non-ketotic T2DM after adjusting for gender and age (P < 0.001 for trend); B: Comparison of serum 2-hour postprandial C-peptide levels among patients with T1DM, ketosis-onset diabetes and non-ketotic T2DM after adjusting for gender and age (P < 0.001 for trend); C: Comparison of homeostasis model assessment index of β-cell function levels among patients with T1DM, ketosis-onset diabetes and non-ketotic T2DM after adjusting for gender and age (P < 0.001 for trend); D: Comparison of homeostasis model assessment index of insulin resistance levels among patients with T1DM, ketosis-onset diabetes and non-ketotic T2DM after adjusting for gender and age (P < 0.001 for trend). FCP: Fasting C-peptide; 2h PCP: 2-hour postprandial C-peptide; T1DM: Type 1 diabetes mellitus; T2DM: Type 2 diabetes mellitus; HOMA2-β: Homeostasis model assessment index of β-cell function; HOMA2-IR: Homeostasis model assessment index of insulin resistance.
