Description of intervention(s) / exposure
This study was a prospective randomized controlled blinded trial. Participating women were randomly assigned to receive either antioxidants cocktail (group I) containing 1000 mg vitamin C, 400 IU vitamin E, 100 micro g Selenium and 1500 IU vitamin A; or identical placebos (group II) in form of oral capsules. This supplementation was given daily from enrolment to delivery and was continued even after pre-eclampsia or hypertension was diagnosed. Participating women were seen once a month for clinical evaluation according to the standardized antenatal care protocol. The definition of pre-eclampsia was in accordance with the American College of Obstetricians. In the last visit in the first and second trimester, and immediately before delivery blood samples were drawn for laboratory investigations.
