Proportional hazards regression models predicting for all-cause mortality in men with CKD
| Exposure | Crude Hazard Ratio (95% CI) | Adjusted Hazard Ratio (95% CI) |
|---|---|---|
| All CKD men (n=506) | ||
| Two-point increase in Mediterranean diet score | 0.77 (0.63 to 0.93) | 0.82 (0.69 to 1.01) |
| Adherence groups | ||
| Low (Mediterranean diet score=1–2) | Reference | Reference |
| Medium (Mediterranean diet score=3–5) | 0.69 (0.50 to 0.97) | 0.75 (0.52 to 1.06) |
| High (Mediterranean diet score=6–8) | 0.72 (0.42 to 1.24) | 0.77 (0.44 to 1.36) |
| P for trend | 0.03 | 0.10 |
| Adequate reporters (n=250) | ||
| Two-point increase in Mediterranean diet score | 0.73 (0.54 to 0.99) | 0.66 (0.48 to 0.90) |
| Adherence groups | ||
| Low (Mediterranean diet score=1–2) | Reference | Reference |
| Medium (Mediterranean diet score=3–5) | 0.56 (0.35 to 0.92) | 0.48 (0.29 to 0.80) |
| High (Mediterranean diet score=6–8) | 0.54 (0.24 to 1.26) | 0.42 (0.18 to 1.02) |
| P for trend | 0.02 | 0.005 |
Data are presented as hazard ratio (95% confidence interval [95% CI]). Covariance in the adjusted models includes body mass index, physical activity, smoking status, education, hypertension, hyperlipidemia, and diabetes.
