COH-QOL-CRC = City of Hope Quality of Life-Colorectal Cancer
PA min = “physical activity minutes” calculated as moderate minutes/week + 2 × vigorous minutes/week
Predicted mean (SE) adjusted for age, sex, years since surgery, ostomy status, income over $50,000, and Charlson-Deyo score ≥ 2
Norm-based scores with mean = 50 and SD = 10
p < 0.05 Trend across ordered weighted PA-minute categories, Bonferroni adjusted
p < 0.05 compared to completely sedentary group, Bonferroni adjusted
p < 0.01 compared to not active group, Bonferroni adjusted
Exceeds minimally important difference (MID) compared to not active group (0.88 for mCOH-QOL-CRC scales, 2.0 for PCS and MCS, 8.0 on 0–100 scale for health domain scales)
