Following the analysis of the association between the health checkup parameters and vitamin D, parameters such as female (t = 4.447, p < 0.005), basophils (t = −4.765, p < 0.005), albumin (t = 4.116, p < 0.005), modification of diet in renal disease (MDRD) (t = −2.38, p < 0.05), and LDH (t = 2.239, p < 0.05) were investigated, and the statistically significant effect was confirmed (Table 4). This evidence concerns the gene ALB and kidney disorder.
