Power generation (watts, normalized to lean body mass) over time based on therapy received for early-stage breast cancer, a local therapy only; b endocrine therapy as the only systemic therapy; or c chemotherapy ± endocrine therapy. The green line represents a “functional norm” of power generation of 2.4 watts/kg lean body mass [14]. Power dropped significantly between baseline and 6 months in all cohorts (A: p = 0.04, B: p = 0.008, and C: p = < 0.001). * = p < 0.05
