^a#, patient number; M, male; F, female; DM, diabetes mellitus; MTP, metatarsophalangeal joint; PAD, peripheral arterial disease; ΔT1, difference between mean temperature of ipsilateral and contralateral foot; ΔT2, difference between mean temperature of ROI and corresponding contralateral ROI; ΔT3, difference between mean temperature of ROI and mean temperature of ipsilateral foot.

^bBetween brackets: Ulcer classification according to University of Texas wound classification.

^cFor patients without complications, left foot was defined as ipsilateral foot.

^dThe ROIs in patients with diffuse complications were their ulcer locations.

^eOnly one complication of patient 9 is shown. In Figure 3 it can be seen that another ROI (abundant callus on first metatarsophalangeal joint) is present on the right foot. However, as there was no contralateral metatarsophalangeal joint 1 due to amputation, this ROI is not further analyzed.
