Logistic analysis on the contribution of rs4588 in different genotypic models to the vitamin D (VD) statuses after adjusting for (gender,) age, body mass index, sampling month, smoking status, sunshine exposure time, sun protection use, and total vitamin D intakes. a, d, and g are VD insufficient (VDI) vs VD deficient (VDD), b, e, and h are VD sufficient (VDS) vs VDD, and c, f, and i are VDS vs VDI in both genders, male, and female, respectively. Data are odds ratio (OR, represented by ○, △, ●, and▲) ± 95% of confidential interval (CI). ○, P ≥ 0.1; △, 0.05 ≤ P < 0.1; ●, 0.01 ≤ P < 0.05; ▲, P < 0.01. Add., additive model; Alle., allelic model; Dom., dominant model; Hom., homozygous model; Rec., recessive model
