Table 2 Pearson correlations of dietary vitamin D and calcium with measures of insulin and glucose metabolism

From: Vitamin D intake is associated with insulin sensitivity in African American, but not European American, women

  Vitamin D    Calcium   
  All AA EA All AA EA
Fasting glucose -0.03 -0.13 -0.01 -0.001 -0.07 -0.12
Fasting insulin -0.11* -0.20  0.01 -0.08 -0.10 -0.03
HOMA-IR -0.11* -0.21  0.01 -0.08 -0.10 -0.05
SI  0.15  0.17*  0.06  0.26  0.15  0.13
  1. Pearson correlation coefficient (r) is reported. Abbreviations: FSIGT, frequently-sampled intravenous glucose tolerance test; AA, African American; EA, European American; HOMA-IR, homeostasis model assessment of insulin resistance; SI, insulin sensitivity index. Statistical analyses were performed on log10-transformed data for SI, vitamin D, calcium, HOMA-IR, fasting glucose, and fasting insulin.
