Fasting blood samples (12 to 14 h) were collected from an arm vein while subjects were reclining in a blood sampling chair, into tubes containing EDTA-Na2 at a final concentration of 0.15%. Plasma was obtained by centrifugation at 1000 g … Continue reading →
Study visits were every two weeks for the first month, then once a month for the remaining six months of the study.
Because the study was an explanatory trial, it was determined a priori to exclude from the main analysis patients with compliance less than 90% of prescribed medication (questioning, counting of tablets), patients with clinical or laboratory adverse effects requiring discontinuation … Continue reading →
