Question 4 An allergy to peanuts is increasingly comment in Western countries. A randomized controlled trial enrolled infants with a diagnosed peanut sensitivity. Infants were randomized to either avoid peanuts or consume them regularly until they reached age 5. At the end of the study 18 out of the 51 randomized to avoidance were allergic to peanuts compared to 5 out of the 47 randomized to consuming them regularly. 4.a) Estimate the difference between the two proportions.

61 2.2 Waived Consent in a Breast Cancer Trial In the case below, British researchers persuaded an ethics committee that a particular trial should not involve informed consent because the information to be comveyed in that process would be hurtful to the subjects. However, a subject learned later that she had been involved in the trial without her knowledge or consent. This disclo sure opens the question of whether informed consent should ever be waived and, if so, whether justifications...

Investigators wish to design a randomized trial to compare low-intensity versus full-dose warfarin for the prevention of recurrent venous thromboembolism (VTE). From a previous study, investigators believe that the risk of recurrent VTE in patients on low-intensity warfarin over a follow-up period of 3 years will be about 8%. They also expect full-dose warfarin to have a lower risk of recurrence (although possibly with additional side-effects such as bleeding complications). Using equal numbers of subjects in each treatment group, they...

Clinical trials are usually conducted in phases that build on one another. Each phase is designed to answer certain questions. Knowing the phase of the clinical trial is important because it can give you some idea about how much is known about the treatment being studied. There are pros and cons to taking part in each phase of a clinical trial. Phase I clinical trials: Is the treatment safe? Phase I studies of a new drug are usually the first...
