| | Response | Predictor | Coefficient (95% CI) | Standard error | value |
| Model 1: log length of stay,
including outliers () | Delirium | 0.40 (−0.09 to 0.88) | 0.24 | 0.11 | | Age | 0.01 (−0.01 to 0.03) | 0.01 | 0.35 |
| Model 2: log length of stay,
excluding outliers () | Delirium | 0.13 (−0.34 to 0.60) | 0.24 | 0.57 | | Age | 0.01 (−0.01 to 0.03) | 0.01 | 0.34 |
| Model 3: log total cost,
including outliers () | Delirium | 0.72 (0.25 to 1.19) | 0.24 | <0.01 |
| Model 4: log total cost,
excluding outliers () | Delirium | 0.46 (0.02 to 0.90) | 0.22 | 0.04 |
