Comparison of serum 25-hydroxyvitamin D (25OHD) and calcium levels between female participants without fibroids and patients with fibroids grouped according to fibroid size.

Study group	Characteristic
	Serum 25OHD level, ng/ml	Statistical significance	Serum calcium level, mmol/l	Statistical significance
Without fibroids	20.73 ± 6.99(n = 267)	P < 0.05	2.39 ± 0.09(n = 116)	P < 0.05
With fibroids < 3 cm	18.47 ± 6.63*(n = 178)		2.36 ± 0.07*(n = 58)
With fibroids ≥3 cm	17.60 ± 5.22*(n = 101)		2.30 ± 0.09*△(n = 52)

Data presented as mean ± SD.

P < 0.05 was considered statistically significant. *P < 0.05 versus without fibroids. ^△P < 0.05 versus fibroids < 3 cm.
