SAT thickness sums from eight sites measured three times in each of the 20 participants. a SAT thickness sums including embedded fibrous structures (DI) plotted against the mean value of the three observers. Pearson’s correlation coefficient r = 0.997, standard error of the estimate (SEE) = 1.1 mm, and intra-class correlation coefficient (ICC) = 0.998 (95% CI: 0.980–0.999). b SAT thickness sums excluding embedded fibrous structures (DE). r = 0.998; SEE = 1.02; ICC = 0.998 (95% CI = 0.995–0.999)
