After annotation area of ulcer was calculated. Image pixels were used as the unit of analysis because white‐to‐white distance was not measured Physicians’ annotations were evaluated for reliability using DICE similarity coefficient (DSC) and intraclass correlation coefficient (ICC) The DSC is the proportion of twice the number of pixels identified by both graders divided by the sum of pixels identified in each image. The DSC ranges from 0 (no overlap) to 1 (perfect overlap) and a coefficient >0.8 is considered good
