Study Arms (4)
vitamin D deficiency treatment group
EXPERIMENTALpatients with vitamin D deficiency (12 ng/ml ≤ serum 25-hydroxyvitamin D3 \< 20 ng/ml)and uterine fibroids receive 1600 IU/day of vitamin D3 oral capsule for two years
vitamin D deficiency control group
NO INTERVENTIONpatients with vitamin D deficiency (12 ng/ml ≤ serum 25-hydroxyvitamin D3 \< 20 ng/ml)and uterine fibroids receive regular follow-up.
vitamin D insufficiency treatment group
EXPERIMENTALpatients with vitamin D insufficiency (20 ng/ml ≤ serum 25-hydroxyvitamin D3 \< 30 ng/ml) and uterine fibroids receive 800 IU/d of vitamin D3
vitamin D insufficiency control group
NO INTERVENTIONpatients with vitamin D insufficiency (20 ng/ml ≤ serum 25-hydroxyvitamin D3 \< 30 ng/ml)and uterine fibroids receive regular follow-up.
Interventions
Non-Vitamin D3 Drops group Patients in this group would take nothing.
