Fig. 4: Box and whisker plot of IHC score status to NGS results.

A comparison to FC values shows FC of 1.3–1.7 to be equivocal for amplification (A). A comparison to TCN values shows TCN of 4–6 are equivocal for amplification (B). Abbreviations: NGS, next-generation sequencing; FC, fold change; TCN, total copy number.
