From: Time-dependent endpoints as predictors of overall survival in multiple myeloma
Correlation between median values of the time-dependent endpoints (TDEs) and observed median overall survival (OS). Each circle represents a study arm, and the surface area of the circle is proportional to the size of the arm. The nonparametric Spearman’s rank correlation coefficient (ρ) and its level of significance are also reported. Abbreviations: EFS, event-free survival; PFS, progression-free survival; TTP, time to progression.
