Figure 4 OS and PFS with or without intratumoral human epidermal growth factor receptor 2 heterogeneity. Kaplan-Meier curves of OS (left) and PFS (right) in both groups was shown with the median follow-up of 18.5 mo (range, 4.7-88.0 mo). MST and median PST in the Hetero group were significantly worse than those in the Homo group. MST: Median survival time; HR: Hazard ratio; CI: Confidence interval; OS: Overall survival; PFS: Progression-free survival.
