Baseline differences were apparent between participants with diabetes and those without, with regard to age (p < 0.0001), diastolic blood pressure (p = 0.0002), potassium (p = 0.002), uric acid (p = 0.028), prevalent hypertension (p < 0.0001), stage of kidney function (p = 0.013), treatment with ACE inhibitors (p = 0.011) or ARA II (p = 0.043). This evidence concerns the gene ACE and hypertensive disorder.
