TABLE 3.
Predicted percentage of individuals (%) reaching the serum 25-hydroxyvitamin D (25OHD) thresholds 28 and 200 nmol/L respectively (used to derive individual nutrient level 98 (INL98) and upper level (UL) respectively). Modeling with left-truncated normal distribution, right-skewed (0.10), and CV of 0.34, and predicted mean response and predicted upper bound of 95% confidence interval mean response as the mean value of the interindividual distribution respectively for INL98 and UL.
