Remote ischemic preconditioning: outcomes
| Outcomes | rIPC (n = 27) | Control (n = 31) | p value | RR (CI 95%) | Absolute risk reduction | Pearson’s r (CI 95%) | NNT |
|---|---|---|---|---|---|---|---|
| Postoperative ischemia | 17 | 27 | 0.03 | 0.722 (0.525–0.994) | 24.1% | NA | 4.1 |
| Median infarct volume (cm3) | 0.36 (0.0–2.35) | 1.30 (0.29–3.66) | 0.09 | NA | NA | 0.21 (-0.03–0.46) | NA |
| New neurological deficits | 4 | 5 | 1 | 0.918 (0.274–3.078) | NA | NA | NA |
| Worsening of preoperative deficits | 3 | 3 | 1 | 1.148 (0.252–5.222) | NA | NA | NA |
