BMI: body mass index, VAS: visual analog scale, TPC: tender points count, FIQ-R: revised Fibromyalgia Impact Questionnaire, MFI: multidimensional fatigue inventory, FIQ-R.1: level of activity, FIQ-R.2: global impact, FIQ-R.3: symptoms intensity. Linear regression models were adjusted for the covariates age and menopausal state.
