BMI = Body Mass Index (Weight/Height2); Data are expressed as mean (standard deviation) if numerical variables, or as the number of patients and their percentages (%), if categorical; *Fisher Exact Test; Hypertension in obese: (1) Patient reported having hypertension and/or required medication at the time of screening; (2) the patient had a systolic blood level ≥ 140 mmHg and/or diastolic levels ≥ 90 mmHg.
