Values are expressed as mean±standard deviation or median (minimum–maximum).
BMI = body mass index, BSA = body surface area, BP = blood pressure, LDL = low density lipoprotein, HbA1C = Hemoglobin A1C, ms = milliseconds, bpm = beats per minute, NA = Not assessed, HRT = Hormone replacement therapy.
P-values<0.05 are considered statistically significant.
