Neoadjuvant treatment arm-level correlation between PFS rates and 5-year OS. The neoadjuvant treatment arm-level association between (A) 1-year PFS and 5-year OS, (B) 2-year PFS and 5-year OS, (C) 3-year PFS and 5-year OS, and (D) 5-year PFS and 5-year OS. Circle size is proportional to the number of patients in each treatment arm. The solid blue line indicates the fitted weighted linear regression line; the light green zone represents its 95% CI; r indicates the correlation coefficient. PFS, progression-free survival; OS, overall survival; CI, confidence interval.
