Partial Spearman correlation coefficients between vitamin D-related biomarkers among controls^*

Median	Total 25OHD (nmol/L)	Bioavailable 25OHD (nmol/L)	VDBP (mg/L)	PTH (pg/mL)

	62.6	7.5	250.9	35.9
Total 25OHD	1.00	0.62^†	0.18^†	−0.24^†
Bioavailable 25OHD		1.00	−0.59^†	−0.18^†
VDBP			1.00	−0.001
PTH				1.00

Abbreviations: 25OHD, 25-hydroxyvitamin D; VDBP, vitamin D binding protein; PTH, parathyroid hormone.

N=368. Partial correlation coefficients were adjusted for age at blood draw (years, continuous), smoking status (never, past, or current smoker), fasting status (yes/no), time of blood draw (collection 1: 06/1989-10/1989, 11/1989-03/1990, 04/1990-07/1990, or 08/1990-03/1991; collection 2: 03/2000-07/2000, 08/2000-12/2000, 01/2001-05/2001, or 06/2001-01/2002), BMI (kg/m²: <25.0, 25.0–27.4, 27.5–29.9, 30.0–34.9, ≥35.0), postmenopausal status and hormone use (premenopausal or postmenopausal (never, past, or current menopausal hormone use), physical activity (tertiles), alcohol intake (g/d: 0, 0.1–4.9, 5.0–14.9, ≥15.0), aspirin use (yes/no), MI family history (yes/no), and AHEI score (tertiles).
