Figure 2From: Comparative benefit from small tumour size and adjuvant chemotherapy: clues for explaining breast cancer mortality decline Adjuvant-CMF-related and tumour-size-related absolute recurrence risk reduction (ARR) for 386 early breast cancer patients undergoing mastectomy only or mastectomy plus adjuvant CMF. Adjuvant-CMF-related ARR = Recurrence risk for controls - Recurrence risk for CMF treated patients. Tumour-size-related ARR = Recurrence risk for T1 – recurrence risk for T2/T3.Back to article page
