Fig. 1.

Distribution of patient and clinician METs assessment results across the study population. This figure illustrates the distribution of patient and clinician categorical metabolic equivalents of task (METs) assessment results across the study population. Here, patient METs self-assessment results were determined from their scored responses to the Duke Activity Status Index (DASI), which generates a numerical METs calculation. The categorical distribution of the DASI results is shown in the blue columns. Clinician METs assessments were carried out and documented in accordance with the standard practice at our Preoperative Evaluation Center (PEC). The distribution of clinician categorical METs assessments for the study population is displayed in the red columns
