Intraobserver and interobserver variability was evaluated using the kappa statistic. As prevalence bias was found in the distribution of the results for intraobserver variability (marked imbalance in the frequency of the category assigned by the assessors due to the higher frequency of a response category) in the category "nodule shape", when evaluating for the prevalence indices and the asymmetry index in the agreement, the prevalence-adjusted bias-adjusted kappa (PABAK) was obtained, corresponding to the value that the kappa would take in the absence of bias and with equal prevalence of the categories. For the interobserver variability of the ACR TI-RADS category, which has five response possibilities, quadratic weighting was selected for two reasons: first, the more response possibilities, the greater the potential for discrepancies, which underestimates the true concordance; and, second, they wanted less penalisation of discrepancies between responses with neighbouring categories (e.g. where one assessor assigned the category ACR TI-RADS 1 and the other assigned the category ACR TI-RADS 2) and more penalisation of discrepancies between responses with non-neighboring categories (e.g. ACR TI-RADS 1 and ACR TI-RADS 4).
