Figure 4. Kaplan-Meier survival curves of all limb amputees according to level of amputation (proximal leg = pelvis, hip, or transfemoral and proxi-mal arm = forequarter, shoulder, or transhumeral [n = 74]; knee disar-ticulation [n = 32]; or distal leg = transtibial, ankle, or foot and distal arm = transradial or wrist [n = 119]).
