Linear regression analysis with HGI as the dependent variable
| Independent variable | β coefficient | 95% CI | P value |
| 2 h glucose increment (mg/dL) | |||
| Model 1 | 0.002 | 0.002 to 0.003 | <0.001 |
| Model 2 | 0.002 | 0.002 to 0.003 | <0.001 |
| Model 3 | 0.002 | 0.001 to 0.003 | <0.001 |
| Model 4 | 0.003 | 0.002 to 0.003 | <0.001 |
Model 1, unadjusted. Model 2, adjusted for age and sex. Model 3, adjusted for variables in model 2 plus body mass index and waist circumference. Model 4, adjusted for variables in model 3 plus smoking, total cholesterol, HOMA-IR, and HOMA-β.
HGI, hemoglobin glycation index; HOMA, homeostasis model assessment; IR, insulin resistance.
