Higher score = worse cognitive function. Covariates are age, treatment arm, assessment, and assessment–treatment arm interaction CFS cognitive function score, SE standard error
For standard treatment with doxorubicin and cyclophosphamide (AC), mid-treatment, day 29; end of the treatment, 4–5 months; for treatment with cyclophosphamide, methotrexate, and fluorouracil (CMF): mid-treatment, day 77; end of the treatment, 6–7 months
For treatment with capecitabine: mid-treatment, day 63; end of the treatment, 4–5 months
p value compares standard and capecitabine treatment arms; a type 1 error rate was adjusted to 0.01 to reduce the chance of spurious significant findings
