(y/n) If Yes, Provide Data Time between Biomarker Sampling and Analysis Season/Date when the biomarker samples were drawn Background exposure data
19056900 Sneve 2008 25(OH)D electrochemiluminescence Yes: according to producer, the assay has, for total analytical precison, a coeff of variation ≤7.8% as judged in any of three different concentrations (48.6 – 73.8 – 177.0 nmol/L) nd nd Vit D intake (mcg/day)=8.9(6.6)
Serum 25(OH)D (nmol/L)=53.1(16.9)
Dietary calcium intake FFQ nd nd Serum Ca was measured at baseline and at 3, 6, 9, and 12 months. Urine for measurement of Ca excretion was collected for 24 hr at baseline and at the end of the study. nd nd Ca intake (mg/day)=940(398)
Serum Ca(mmol/L)=2.31(0.11)
