Note: Student t test and analysis of variance with overall F and Duncan multiple range test used. FACT‐C‐TOI (0 − 84: higher score = better health‐related quality of life), SF‐36 Vitality T‐score (higher score = more vitality), FACT‐NTX13 (0–52: higher score = greater toxicity), FACT‐NTX4 sensory (0–16: higher score = greater toxicity), NSABP SCL‐17 (0–100: higher score = greater symptom bother).
Abbreviations: 5‐FU, 5‐fluorouracil; CAPE, capecitabine; NSABP SCL‐17, National Surgical Adjuvant Breast and Bowel Project Symptom Checklist; NTX, neurotoxicity; OXA, oxaliplatin; SF‐36, Short‐Form 36‐item Survey; TOI, Trial Outcome Index.
(KPS 90–100) Fully active, able to carry on all predisease performance without restriction; (KPS 70–80) restricted in physically strenuous activity but ambulatory; (KPS 50–60) ambulatory and capable of all self‐care but unable to perform any work activities.
Means sharing the same superscript letter (a, b, c) for a variable within a column do not differ significantly using Hochberg multiple comparison adjustment, p < .05.
