Table 2. Multivariable logistic regression. Pre-ERAS vs. post-ERAS satisfaction.
| Post-operative satisfaction | Odds ratio | Std. Err. | P > t | 95% Conf. Interval |
|---|---|---|---|---|
| Post-ERAS | 2.5 | 0.94 | 0.016* | 1.2–5.3 |
| Smoker | 0.98 | 0.3 | 0.9 | 0.6–1.7 |
| Pre-operative pain leg (0–10 VAS score) | 0.94 | 0.06 | 0.4 | 0.8–1.1 |
| Age (years) | 0.99 | 0.01 | 0.9 | 0.98–1.01 |
| Number of levels | 1.04 | 0.2 | 0.07 | 0.7–1.5 |
Multivariable logistic regression. Adjusted by age, gender, smoking status, pre-op leg pain (VAS score), type of surgical intervention and number of levels of intervention. *, P values ≤0.05 statistically significant. ERAS, enhanced recovery after surgery.
