OS: Overall Survival. DFS: Disease Free Survival. HR: Hazard Ratio.
^{^}11 trials had HR data for OS and only 8 trials had HR data for DFS.
⁺Less than half the number of patients assessed were available for DFS results, and therefore, no statistical pooling analysis was undertaken.
^#9 trials had HR data for OS and only 7 trials had HR data for DFS.
*6 trials had HR data for OS and only 5 trials had HR data for DFS.
