One-way sensitivity analysis graph of the probability of foot saved over a range from 0.20 to 0.80 to see if it changes the result of the decision analysis in Tip 1. If the probability of foot saved is less than 0.34, below knee amputation (BKA) is the better option. If the probability of foot saved is over 0.34, the better option is to use antibiotics and debridement. The threshold for the decision change is 0.34.
