  1. Multivariate analysis was performed with factors significantly associated with ≥30 ng/ml of serum 25-hydroxyvitamin D3 levels by univariate analysis (p < 0.10). We defined the cases that serum 25-hydroxyvitamin D3 levels were measured between May and October as warm season. gamma-GT gamma-glutamyltaransferase
