SBP values in insulin-treated, vitamin D-treated, and combined insulin and vitamin D-treated groups were significantly lower than that in DN group (139.17 ± 5.27, 166.33 ± 8.17, 117.33 ± 3.56 mmHg, respectively; P < 0.05) and significantly higher than that in control group (P < 0.05). Here, INS is linked to liver dysplastic nodule.
