Figure 4. Predicted probability of mortality or major morbidity according to Gait Speed and the Society of Thoracic Surgeons (STS) risk score.

Slow gait speed (solid circles) conferred a 2- to 3-fold increase risk for any given level of STS predicted mortality or major morbidity compared with normal gait speed (open circles). The adjusted odds ratio for mortality or major morbidity was 3.05 (95%CI: 1.23–7.54). Reproduced with permission, Elsevier.[96]
