A: Oxy and deoxy values for healed and nonhealed DFUs. The diagonal solid line represents the decision line for a healing algorithm based on oxy and deoxy values. Ninety percent of points lying to the right of the line healed. The diagonal dashed line represents a second decision line where 87% of the points (seven of eight excluding calluses) lying to the left of the line did not heal. B: Probability of healing based on HTOM healing index for healed and nonhealed DFUs. An ulcer with a positive healing index has a higher likelihood to heal. ♢, Ulcers with underlying osteomyelitis that did not heal; ♦, ulcers that did not heal at 24 weeks; ○, ulcers that healed and were surrounded by callus; , ulcers that healed at 24 weeks. arb, arbitrary.
