Association between RDW and risk of major composite cardiovascular outcomes in various adjustment models
| Model | Presence of RDW ≥ 14.5% | ||
|---|---|---|---|
| HR | 95% CI of HR | P value | |
| Model 1, unadjusted model | 3.22 | 2.01–5.15 | <0.001 |
| Model 2, adjusted for age, gender | 3.15 | 1.94–5.12 | <0.001 |
| Model 3, further adjusted for diabetes mellitus, hypertension, smoking | 3.14 | 1.92–5.13 | <0.001 |
| Model 4, further adjusted for total cholesterol, HDL, Systolic BP | 3.25 | 1.99–5.31 | <0.001 |
| Model 5, further adjusted for hemoglobin, albumin | 2.83 | 1.70–4.70 | <0.001 |
| Model 6, further adjusted for creatinine, LVEF | 2.58 | 1.54–4.32 | <0.001 |
