FIRST = ford insomnia response to stress test. Medical menopause = menopause due to medical treatments including complete or partial hysterectomy, chemotherapy, or endometrial ablation.
ISI % is proportion that is ISI ≥ 11. All other sleep parameters collected using the consensus sleep diary. One-way ANOVAs used to compare pretreatment means, with Bonferroni post hoc comparisons.
