Bonferroni post hoc pairwise comparisons showed that for tumor size, the ADC values were significantly lower in group 1 than those in group 2, for PR, the ADC values were higher in group 1 than those in group 3, and for HER2, the ADC values were higher in group 3 than those in group 1 or group 2 (Fig. 1). Here, PGR is linked to neoplasm.
