| ASA level | 2 vs. 1 | 1.90 | 1.43 | 2.51 | <0.0001 |
| 3 & 4 vs. 1 | 3.61 | 1.47 | 8.85 | 0.0050 | |
| Sedation time (mins) | Continuous | 1.02 | 1.00 | 1.04 | 0.0413 |
| Procedure type | Upper vs. lower endoscopy | 4.33 | 2.23 | 8.44 | <0.0001 |
| Upper & lower vs. lower endoscopy | 3.33 | 2.20 | 5.04 | <0.0001 | |
| Adverse events | Yes vs. no | 1.95 | 0.59 | 6.50 | 0.27 |
| CRNA | Yes vs. no | 1.12 | 0.64 | 1.98 | 0.69 |
Total procedure cases = 258, performed by 21 anesthesiologists.
The model was multivariate logistic regression, incorporated with generalized estimating equation (GEE) to account for potential correlations between repeapted measures by anesthesiologists.
