| Procedure time (mins) | Continuous | 0.98 | 0.03 | 0.93 | 1.03 | <0.0001 |
| Procedure type | Lower endoscopy vs. Upper endoscopy | 0.2 | 1.2 | −2.2 | 2.6 | 0.88 |
| Both vs. Upper endoscopy | 2.2 | 1.3 | −0.4 | 4.7 | 0.10 | |
| Adverse events | Yes vs. No | 3.1 | 2.0 | −0.9 | 7.0 | 0.13 |
| Endotracheal intubation | Yes vs. No | 1.8 | 0.8 | 0.2 | 3.3 | 0.0229 |
| CRNA | Yes vs. No | −1.3 | 1.3 | −3.8 | 1.2 | 0.31 |
Total procedure cases = 258, performed by 21 anesthesiologists.
The model was multivariate normal regression, incorporated with generalized estimating equation (GEE) to account for potential correlations between repeapted measures by anesthesiologists.
