| Â | Double-blind - Wikipedia, the free encyclopedia |
 | | It is also difficult to use the double blind method to compare surgical and non-surgical interventions (although sham surgery, involving a simple incision, might be ethically permitted). | | | The Double blind method is an important part of the scientific method, used to prevent research outcomes from being 'influenced' by the placebo effect or observer bias. | | | Blinded research is an important tool in many fields of research, from medicine, to psychology and the social sciences, to forensics. |

| Â | "double blind, placebo-controlled trial" |
| | The "double-blind" is the procedure in the study design which makes every attempt to ensure that neither the patient nor the researchers are aware which drug (active or placebo) each subject is receiving. | | | I am sure many of the members of the society are aware that the research team at Prince Henry/Prince of Wales Hospitals has conducted a number of "randomised, double blind, placebo-controlled trials" assessing potential treatment options for patients with CFS. | | | The "blind" is very important in this type of research as it ensures that neither the patients nor the researcher can have any direct effect on the outcome of the treatment due to factors such as the effect of believing that one is receiving the active drug which in itself may produce some benefit. |

| | For this reason the professional opinions of practicing doctors are far less reliable than the outcomes of double-blind, placebo-controlled studies. | | | Some can be prevented by using blinded evaluators; in other words, the acupuncturists know who is receiving real treatment, but a separate researcher evaluates how well participants have improved, and that researcher has no idea who received real treatment. | | | A top quality study will report on the success researchers had in efforts to keep the participants "blind." Surprisingly, many studies of medications reported in prestigious medical journals fail to do so. |

| | The evaluation of such procedures can be approximately double-blind if the researchers responsible for recording subjects' responses and analyzing the data are blinded. | | | Strictly speaking, every researcher who interacts with or treats a subject should be blinded, if an experiment is to be designated "double-blind." This situation is easily arranged when the treatment being tested is a drug, the appearance of which may be simulated with a colored pill or solution (that is, a placebo). | | | Performing an experiment in double-blind fashion is a way to lessen the influence of prejudices and unintentional physical cues on the results. |

| Â | Double-blind placebo-controlled study |
| | The best and most reliable form of research is the double-blind placebo-controlled study. | | | This last part is important, because it prevents the researchers from unintentionally tipping off the study participants, or unconsciously biasing their evaluation of the results. | | | A treatment cannot really be said to be proven effective unless it has been examined in properly designed and sufficiently large studies of this type. |

| | Both of these supplements have been studied since the early 1980s, but with an increasing interest in alternative remedies that can perhaps offer a natural solution to a medical problem, the medical and scientific community has taken a much more active approach in researching these topics. | | | Results indicate a better than 80 percent control of pain within six weeks for those patients using MSM, while only two patients showed a minimal improvement (less than 20 percent) on the placebo(7). | | | A just released study done over three years demonstrated virtually the same findings(3), further validating the use of Glucosamine for stimulating cartilage growth and joint pain. |

I will identify some popular belief systems that involve magical thinking and indicate some recent scientific studies that suggest that we are dealing with innate principles of cognition. | | | So perhaps our outrage might be tempered by the realization that, given the huge numbers of Americans who have consulted "alternative" or "complementary" medical practitioners, the government has an obligation to support research into their effectiveness. | | | This was explained in reference to the "cephalic phase" of the digestive process, affecting the flow of enzyme-laden salivary, gastric, pancreatic, and intestinal secretions. |

| | Thus, a treatment can only be considered proven effective when there have been several double-blind studies enrolling 200 or more people, performed by separate researchers, conducted according to the highest standards (as measured by a study rating scale called the “Jadad scale”), carried out at a respected institution and published in a peer-reviewed journal. | | | There are a number of pitfalls in designing, performing, and reporting such studies, and for this reason some double-blind studies deserve more credence than others. | | | The double-blind study is thus much more than a requirement for absolute proof of efficacy (as is commonly supposed) — it is a necessity for knowing almost anything about whether a treatment really works. |
