Figure 5. Lack of correlation between Gait Speed and the Society of Thoracic Surgeons (STS) risk Score, reflecting distinct domains.
Lack of correlation between gait speed and STS score (R = 0.14, P = 0.13), showing that gait speed represents a distinct domain. In addition, there was no correlation between gait speed and age or left ventricular ejection fraction. Reproduced with permission, Elsevier.[96]
