Model Details: This study was a randomized, double-blind, placebo-controlled clinical trial on 40 outpatients with hypertension and type 2 diabetes were recruited. Patients were allocated into two equal groups of 20 by computer-generated randomly permutated codes. the subjects were randomly assigned to 1 of 2 groups: Group 1 received a single dose (100.000 IU) of oral supplementation with cholecalciferol (vitamin D3). Group 2 received matching placebo capsules containing microcrystalline cellulose.
