Figure 2. Correlation of EGFR amplification by FISH with copy number (CN) determined by WES.

Figure 2.

X-axis, geometric mean of EGFR copy number (all exons except exons 2–7); linear scale. Vertical dotted line at 3 delineates EGFR-amplified (to the right) vs –nonamplified samples (to the left) by CN. Y-axis, percentage EGFR amplification by FISH. Cut-off for amplification (≥ 15%) indicated by dotted horizontal line. N = 74 samples.
