Subclonal dynamics between pretherapeutic biopsies and resected tumors of 14 patients; each line depicts an individual patient. Left, pathological regression (percentage reduction of viable tumor cells) following immunotherapy. Center, estimated total number of subclones in the resected tumor. Right, fraction of subclones enriched ('fraction gained') and depleted ('fraction lost') in the resected tumors. Fractions are visualized by color (with yellow for high, purple for low), and bubble size (large for high, small for low, no bubble for zero).
