Quantitative evaluation of inter-observer variability, intra-observer variability and method versus each observer independently (n = 5), reported as mean ± standard deviation. p-values were computed with a paired sample t-test between the inter-observer variability and proposed method for each evaluation measure. ^†Indicates a significant difference (p-value < 0.05, i.e. less than 5% chance that the samples have identical averages).
