Thermal imaging scores and clinical measurements. (A) Box plots with individual measurements of the fractal dimension (FD) (left) and sum of extrema (SX) (right). P value by one-way ANOVA with Tukey’s test for multiple comparisons. (B), (C) The correlation between the thermal FD and SX scores and C-reactive protein (CRP) (B) and D-Dimer (C) measured on the day of imaging. P value by Spearman’s correlation test.
