| | Randomized controlled trial - definition of Randomized controlled trial in Encyclopedia |
 | | A randomized controlled trial (RCT) is a form of clinical trial, or scientific procedure used in the testing of the efficacy of medicine, used because of its record of reliability. | | | In practice, since the researcher knows, it is possible for them to treat the patient differently or to subconsciously hint to the patient important treatment-related details, thus influencing the outcome of the study. | | | The analysis of the trial results is a great skill in itself, and pharmaceutical firms employ groups of statisticians to try to make sense of the data. |

| | The aim is to see if the herb prevents the onset of dementia and, specifically, Alzheimer's disease; slows cognitive decline and functional disability (for example, inability to prepare meals); reduces the incidence of cardiovascular disease; and decreases the rate of premature death. | | | NCCAM is conducting a large clinical trial of ginkgo with more than 3,000 volunteers. | | | Some promising results have been seen for Alzheimer's disease/dementia, intermittent claudication, and tinnitus among others, but larger, well-designed research studies are needed. |

| | Although the animals did not fully recover all their bone density compared to controls, those rats fed oleuropin (0.15g/kg) or olive-oil (50 g/kg) daily for 3 months recovered 70-75% of their bone density—a 50% improvement compared to control animals, which were given 25g/kg peanut oil and 25 g/kg rapeseed oil daily. | | | In this double-blind, cross-over, randomized clinical trial, 30 healthy volunteers were given three similar olive oils whose concentration of antioxidant phenols ranged from 0 to 150 mg/Kg. | | | Their early studies revealed that two olive polyphenols, oleuropin and hydroxytyrosol, greatly lessen the inflammation-mediated bone loss involved in osteoporosis. |
