Data for leptin levels showed a skewed distribution and therefore were log-transformed before analysis. Data are expressed as means±SD. *P<0.05 was considered statistically significant after Student's t-test. ARB: Angiotensin receptor blocker, ACE: Angiotensin-converting enzyme, CCB: Calcium channel blocker, SD: Standard deviation
