2. Fig 1
Linear regression modelling of the relationship between CPETarm and CPETleg for the vascular surgery patient group. The curvature in the linear fits and PIs is a result of fitting a linear regression model to the log-transformed CPETleg. The limits of the 95% PIs give an indication of our uncertainty in predicting CPETleg using CPETarm.

3. Fig 2
Linear regression modelling of the relationship between CPETarm and CPETleg for the healthy volunteer group. The curvature in the linear fits and PIs is a result of fitting a linear regression model to the log-transformed CPETleg. The limits of the 95% PIs give an indication of our uncertainty in predicting CPETleg using CPETarm.
