DA‐decision aid, SD‐standard deviation, IQR‐interquartile range, LMP‐last menstrual period.
Menopause Quality of Life Scale (MENQoL) range (0 symptoms least bothersome to 6 most bothersome).
Short Form (SF) 12 Physical and Mental scales are scored using a norm‐based method to have a mean of 50 and a SD of 10 in the general U.S. population with a higher number worse.
Knowledge and Realistic Expectations are scored out of 100.
Value Scale (range 0–10) higher number more valued.
Decision Conflict Scale (DCS) (range 1–5) higher number more decisional conflict.
Satisfaction with decision (range 0–15), satisfaction with process (range 0–50) higher number more satisfied.
