Glycated hemoglobin is not enough: The role of glycemia risk index for glycemic control assessment in type 1 diabetes

Figure 1 Relationship between the glycemia risk index and other continuous glucose monitoring metrics, glycated hemoglobin. Correlations between pairs of metrics, where 1 indicates a strong correlation and -1 indicates a strong inverse correlation. GRI: Glycemia risk index; TIR: Time in range; TBR: Time below range; Low: Low-glucose hypoglycemia (glucose level: 3.0 mmol/L to < 3.9 mmol/L); VLow: Very-low-glucose hypoglycemia (glucose level: < 3.0 mmol/L); TAR: Time above range; High: High-glucose hyperglycemia (glucose level: 10.0 mmol/L to 13.9 mmol/L); VHigh: Very-high-glucose hyperglycemia (glucose level: > 13.9 mmol/L); CV: Coefficient of variation; MG: Mean glucose; HbA1c: Glycated hemoglobin; GMI: Glucose management indicator; GRI-lo: Hypoglycemia component of glycemia risk index; GRI-hi: The hyperglycemia component of glycemia risk index.
