Fig. 1: Distribution of HER2DX ERBB2 mRNA score.

A Distribution of HER2DX ERBB2 mRNA score groups across the 94 patients. B Distribution of HER2DX ERBB2 mRNA score groups in primary and metastatic tumor. P-value was determined using Fisher’s exact test. C HER2DX ERBB2 mRNA score in primary and metastatic tumors. P-value was determined using an unpaired t-test. D Distribution of HER2DX ERBB2 mRNA score groups in de novo and relapsed disease. The P-value was determined using Fisher’s exact test. E HER2DX ERBB2 mRNA score in de novo and relapsed disease. The P-value was determined using an unpaired t-test.
