Level I Evidence: Randomized Clinical Trial SWOG 8710
FIG. 5: There is a variety of levels of evidence available demonstrating the benefit of neoadjuvant chemotherapy. So-called Level I, highest strength evidence is obtained from a prospectively randomized clinical trial, such as SWOG 8710 (Figure).[2] Even better than data from a randomized clinical trial are data from two randomized clinical trials that show consistent results.
