Fig. 3

Correlation between treatment effects on DFS and OS (related to Table 3) according the sensitivity analysis that restricted to trials with adjuvant therapy versus observation (a) and trials with adjuvant therapy versus adjuvant therapy (b). Each trial is represented by a circle, with the size of the circle being proportional to the sample size. The blue line represents the 95% prediction limit of the regression line (red line). OS, overall survival; DFS, disease-free survival; HR, hazard ratio
