Bias +95% LoA between estimated and actual mean VO2 (ml/kg/min) at four stages of the Chester step test during two separate trials
| Stage I | Stage II | Stage III | Stage IV | |
|---|---|---|---|---|
| Significant difference (Bonferroni corrected alpha = p<0.007) between the estimated and actual VO2 value (*p<0.0005, †p = 0.003, ‡p = 0.001). | ||||
| 95% LoA:act ratio is the ratio of the 95% LoA between actual and estimated VO2 divided by the actual VO2. | ||||
