Multivariate analysis for cardiovascular events (logistic regression analysis)
| Final model | Cardiovascular event c-index (95% CI) | Binary R2 |
|---|---|---|
| Model 3 | 0.729 (0.706 to 0.776) | 0.153 |
| Model 4 | 0.720 (0.689 to 0.763) | 0.144 |
| Model 5 | 0.717 (0.686 to 0.758) | 0.138 |
| Model 1 | 0.698 (0.656 to 0.742) | 0.133 |
Cardiovascular disease risk factors have been removed from the models step by step.
Model 3 included liver brightness, study group, age, gender, smoking, alcohol consumption, systolic blood pressure, LDL-cholesterol level, body mass index and QUICKI. Model 4 included liver brightness, age, gender, smoking, blood pressure and QUICKI. Model 5 included liver brightness, age, gender, smoking and blood pressure. Model 1 included liver brightness, study group, age and gender. C-index with CIs obtained from 250 bootstrap resamplings and binary R2 was used.
LDL, low-density lipoprotein; QUICKI, quantitative insulin sensitivity check index.
