Multivariate logistic regression predicting composite 30-day morbidity
| OR* | 95% CI* | P values* | |
| Composite morbidity current procedural terminology linear risk | 0.38 | 0.36 to 0.40 | <0.0001 |
| Age | 0.99 | 0.98 to 1.00 | 0.07 |
| American Society of Anaesthesiologists class | 1.02 | 1.00 to 1.04 | 0.06 |
| Underweight short | 1.35 | 1.03 to 1.75 | 0.04 |
| Overweight short | 1.43 | 1.06 to 1.89 | 0.01 |
| Underweight tall | 1.32 | 0.81 to 2.22 | 0.30 |
| Overweight tall | 1.00 | 0.81 to 1.25 | 0.97 |
Both composite 30-day morbidity current procedural terminology linear risk and age were continuous variables.
