(A) Box plot shows a significantly higher trastuzumab
(TRA)-Aurelia-1 uptake (mean, 19.25 ± 0.667; max, 1.2; min: 13.3)
in human epidermal growth factor receptor 2 (HER2)–positive human
breast tumors compared with HER2-negative tumors (P =
.002 using Kruskal-Wallis test). (B) Box plot shows a
significantly higher TRA-Aurelia-2 uptake (mean, 16.16 ± 4.793;
max, 20.6; min, 10.7) in HER2-positive tumor tissue in comparison with
HER2-negative tumors (P = .002 using Kruskal-Wallis
test). Error bars describe 95% CI for each data point. (C,
D) Pearson correlation curve data for TRA-Aurelia-1 and
TRA-Aurelia-2 uptake in HER2 tumors shows significant correlation
(r = 0.8, P = .002).
