A multicenter double-blind randomized study was carried out to compare the effect of drug X with that of a placebo in patients surviving acute myocardial infarction (AMI). Treatment with the drug started 7 days after infarction in 1,884 patients, 52% of all persons who were evaluated for entry into the study. 945 participants were randomized to treatment with drug X while 939 were assigned to the placebo group. Patients were then followed for 12 months for reinfarction. There were 152...

> Question 9 3 pts In a randomized, double-blind, placebo-controlled trial of children, echinacea was tested as a treatment for upper respiratory infections in children. "Days of fever" was one criterion used to measure effects. Among 337 children treated with echinacea, the mean number of days with fever was 0.81, with a standard deviation of 1.50 days. Among 370 children given a placebo, the mean number of days with fever was 0.64 with a standard deviation of 1.16 days. Assuming...

A study for the treatment of patients with HIV-1 was a randomized, controlled, double-blind study that compared the effectiveness of ritonavir-boosted darunavir (rbd), the drug currently used to treat HIV-1, with dorovirine, a newly developed drug. Of the 375 subjects taking ritonavir-boosted darunavir, 307 achieved a positive result. Of the 375 subjects taking dorovirine, 321 achieved a positive result. Complete parts (a) and (b). Find the sample percentage of subjects who achieved a positive outcome in each group. The sample...

In a randomized double-blind, placebo-controlled trial of children, an herb was tested as a treatment for upper respiratory infections in children. "Days of fever was one criterion used to measure effects. Among 335 children treated with the herb, the mean number of days with fever was 0.78, with a standard deviation of 1.51 days. Among 387 children given a placebo, the mean number of days with fever was 0.56 with a standard deviation of 123 days. Usea 0.01 significance level...

Classify each of the hypothetical experiments as double blind, single blind, or unblinded. At least one experimental technique will be used more than once. A pharmaceutical company claims that their new eye drop formula is more effective at treating glaucoma than the standard one. A group of doctors decide to test the claim, and they ask their patients to choose which type of eye drop they would like to receive. The doctors keep track of the number of patients prescribed...

Quit Smoking: The New England Journal of Medicine published the results of a double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. With the data from the experiment we calculate the sample difference in the "quit smoking" rates for the nicotine treatment group and the placebo group ("treatment" minus "placebo"). We get 0.8% = 0.008. Which of the following is an appropriate conclusion based on this finding? A. In this experiment the...
