FIGURE 1.

The association between vitamin D concentration in midpregnancy (clinical cut-offs) and developmental stages of the mandibular teeth. The ordinal regression model was fully adjusted for season at blood sampling, maternal age, BMI at intake, ethnicity, education, alcohol consumption, folic acid use, vitamin supplementation, age of child, hypodontia, child BMI and height, calcium and phosphorus intake, child vitamin D concentration, and head BMD; Y-axis represents developmental stages of the mandibular teeth. All the statistically significant data points are presented inside the squares. Optimal (≥75.0 nmol/L; reference); sufficient (50.0–74.9 nmol/L); deficient (25.0–49.9 nmol/L); severely deficient (<25.0 nmol/L). BMD, bone mineral density.
