The primary outcome, residual or recurrent disease within 2 years, occurred less often in NAC group patients: 16.9% (118/699) NAC versus 21.5% (76/354) control. This corresponded to a 28% lower recurrence rate with NAC than control: rate ratio (RR) = 0.72 (95% CI, 0.54 to 0.98, Risk of (A) recurrence or persistent disease, (B) death from colon cancer, and (C) death from any cause: NAC Risk of recurrence was strongly related to histologic regression grade (Fig
