Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Postmenopausal women
Associations of 25(OH)D to adiposity, blood pressure, fasting aldosterone, insulin, glucose and lipid profile, HOMA-IR, parathormone and microvascular function, assessed by laser-Doppler flowmetry at cutaneous site, were investigated.
Blood samples and Microvascular function assessment evaluated through laser-Doppler flowmetry by the LASER speckle contrast analysis (LASCA) device
We enrolled 39 non-smokers, low CVR postmenopausal women, with less than 10 years of hypoestrogenism. Associations of 25(OH)D to adiposity, blood pressure, fasting aldosterone, insulin, glucose and lipid profile, HOMA-IR, parathormone and microvascular function, assessed by laser-Doppler flowmetry at cutaneous site, were investigated
