NOTE. For doxorubicin, main LE is cardiac dysfunction; for paclitaxel and oxaliplatin, main LE is peripheral neuropathy; for cyclophosphamide, main LE used in model is premature menopause. Bold font indicates P < .05.
Abbreviations: LE, late or long-term effect; OR, odds ratio; PCP, primary care provider.
No. is slightly smaller than 1,130 because of missing information for variables of interest.
