30-Day perioperative unadjusted and adjusted risk ratios for patients assigned to carotid endarterectomy (n = 744) with CKD compared to those without CKD
| Parameter | Unadjusted Risk Ratio (95% CI) | P | Adjusted Risk Ratio (95% CI) | P |
|---|---|---|---|---|
| Any stroke or death | 1.08 (0.61 to 1.90) | 0.79 | 1.30 (0.73 to 2.33) | 0.37 |
| Any nonfatal stroke | 0.87 (0.45 to 1.69) | 0.68 | 1.09 (0.54 to 2.20) | 0.81 |
| Death (any cause) | 2.55 (0.69 to 9.40) | 0.16 | 2.67 (0.91 to 7.84) | 0.07 |
| MI, CHF, or arrhythmia | 5.43 (2.15 to 13.71) | <0.001 | 3.98 (1.60 to 9.90) | 0.003 |
| MI | 3.39 (0.82 to 14.09) | 0.09 | 3.14 (0.81 to 12.23) | 0.10 |
| CHF | 8.14 (0.92 to 72.4) | 0.06 | 5.82 (0.77 to 44.07) | 0.09 |
| Arrhythmia | 6.11 (1.67 to 22.37) | 0.006 | 3.99 (1.17 to 13.65) | 0.027 |
Includes patients who had moderate and severe stenoses at time of randomization and actually had surgery. Patients with and without CKD were compared using log-binomial regression. Patients without CKD served as the referent group. Risk ratios were adjusted for age, gender, and a history of hypertension, MI, or smoking.
