Relationship between overall survival hazard ratio (OS HR) and time to progression/progression-free survival HR (TTP/PFS HR) among all trials. Each trial is represented by a circle, with its size proportional to the number of patients. TTP/PFS HR was strongly correlated with OS HR (R = 0.73, p < 0.001) on the basis of weighted linear regression (*).
