Table 2 shows the distribution of serum 25OHD levels, according to the categorization of deficiency, insufficiency, and sufficiency. Serum PTH and bone alkaline phosphatase levels were higher in patients with 25OHD deficiency (57.65 ± 22.68 g/mL and 29.50 ± 14.04, U/L respectively), compared with patients with insufficiency (45.88 ± 19.8 pg/mL and 23.47 ± 8.8 U/L, p < 0.05 and p < 0.05 respectively) and sufficiency (47.13 ± 16, p = 0.062 and 22.14 ± 9.7, p < 0.05 respectively). Here, PTH is linked to hyperinsulinemic hypoglycemia, familial, 4.
