Table 1.

Representative Probabilities to be Assigned to All Outcomes Represented in the Decision Tree in Tip 1

Outcomes	Probability
Probability of foot saved using antibiotics	0.50
Probability of full recovery after foot saved	0.80
Probability of recovery with limp after foot saved using antibiotics	0.20
Probability of death after infection is not controlled by antibiotics	0.10
Probability of above the knee amputation if infection not controlled by antibiotics	0.80
Probability of below the knee amputation if infection not controlled by antibiotics	0.10
Probability of survival after immediate below knee amputation	1.00

The probabilities all pertain to the branch of the tree corresponding to the choice of initial antibiotic therapy without amputation. These probabilities are best derived from published papers or documented individual or institutional case experience
