Summary of the equivalence test performed to determine the level of minimum equivalency between each method and the detailed TCM method, which is considered the reference. For example, in the case of adult female chest breasts, the mean of longitudinal approximated TCM method and detailed TCM method are equivalent within 3% with a significant p-value (0.0001) <0.05, indicating that the alternative hypothesis is accepted, i.e., the data sets are similar.
