# Morphological Foot Model for Temperature Pattern Analysis Proposed for Diabetic Foot Disorders
## 3 Results and Discussion
### Foot Model Extraction  
The overlap measures corresponding to the foot models extracted, considering each subject as reference, were averaged and listed in Table 2. As explained in the previous section, although the model extraction was performed separately for each foot, the overlap measurements are displayed together for comparison purposes.

Table 1: Overlap measures at each time point for the ground truth masks associated with the right and left feet. Average values and their corresponding standard deviations are expressed as percentages.  
The coefficients of variation (CV) for most of the overlap measures, estimated as the ratio between the standard deviation and the mean, were below 0.4% and 0.25% for the female and male models, respectively. An exception was observed for the incorrectly detected conditions, \(FP\), and the incorrectly rejected conditions, \(FN\), in which the CVs were up to 3% and 5% for the female and male models, respectively.  
According to [PERSON]'s matched-pairs test, for the left foot in the female model, significant longitudinal differences (\(p<0.05\)) were found for specificity and \(FN\) between T0 and T10. For the male model, significant longitudinal differences (\(p<0.05\)) were found among the overlap measures for the left foot between the baseline, T0, and the subsequent time points, T5, T10, T15. However, for specificity and \(FN\), significant changes were not detected. Regarding the right foot, no longitudinal changes were observed for the associated overlap measures for any of the models.  
For the female model, intergroup differences were found at all time points for specificity and \(FN\), which were significantly higher for the right foot as compared to the left one (\(p<0.01\)). Similarly, sensitivity and \(FP\) were significantly higher for the right foot but only at T10 and T15 (\(p<0.01\)). For the male model, intergroup differences were found at all the time points for all the overlap measures (\(p<0.05\)), which, as observed for the female model, presented higher values for the right foot. An exception was found at T15 in which specificity and \(FN\) presented comparable values for both feet.
