Textbook Question
Chapter 8, Problem 120P
study was recently reported comparing the effects of different dietary patterns on blood pressure within an 8-week follow-up period [16]. Subjects were randomized to three groups: A, a control diet group, N = 154; B, a fruits-andvegetables diet group, N = 154; C, a combination-diet group consisting of a diet rich in fruits, vegetables, and lowfat dairy products and with reduced saturated and total fat, N = 151. The results reported for systolic blood pressure (SBP) are shown in Table 8.29.
Table 8.29 Effects of dietary pattern on change in SBP
Making the same assumption as in Problem 8.118, compute the 95% CI from the information provided.
8.118 Suppose we assume that the standard deviation of change in blood pressure is the same in each group and is known without error. Compute the exact p-value from the information provided.

A 2017 article in The New England Journal of Medicine details the results of a randomized clinical trial designed to evaluate the efficacy of a rotavirus gastroenteritis vaccine designed for infants. As per the authors:
“Each year, rotavirus gastroenteritis is responsible for about 37% of deaths from diarrhea among children younger than 5 years of age worldwide, with a disproportionate effect in sub-Saharan Africa. We conducted a randomized, placebo-controlled trial in Niger to evaluate the efficacy of a live, oral bovine rotavirus pentavalent vaccine (BRV-PV, Serum Institute of India) to prevent severe rotavirus gastroenteritis. Healthy infants received three doses of the vaccine or placebo at 6, 10, and 14 weeks of age. Episodes of rotavirus gastroenteritis were assessed through active and passive surveillance.”
The following Kaplan-Meier curves show the time to a diagnosis of rotavirus gastroenteritis separately for the vaccine and placebo samples. Infants were followed for up to 60…
The researchers sought to explore the connection between dietary fat consumption and the incidence of cardiovascular disease (CVD) events in a cohort of 5,115 young adults of both Black and White backgrounds. In 1985, these individuals underwent an initial examination. Over the subsequent 35 years, those who were initially free of disease were monitored to investigate the potential associations between their dietary fat intake and the occurrence of CVD events. Among the 2,100 young adults who had a high-fat diet at the start of the study, 255 experienced a new CVD event. Among the 3,015 young adults who did not have a high-fat diet at baseline, 125 experienced a new CVD event during the follow-up period.
Risk of CVD events among those with a high-fat diet is ____.
Risk of CVD events among those without a high-fat is ____.
The relative risk is ____.
A 2012 article in the New England Journal reports the results of a randomized trial to assess the association between regular usage of asthma medication prior to turning 18 years old, and height at age 18 years. As per the authors,
"From December 1993 through September 1995, we randomly assigned 1041 children between the ges of 5 and 13 years with mild-to-moderate asthma to one of three study groups in the double-blind, placebo-controlled CAMP trial."
(reference: Kelly H, et al. Effect of Inhaled Glucocorticoids in Childhood on Adult Height. New England of Medicine (2012). 367 (10))
The random assignment groups were Budesonide, Nedocromil and placebo. The following graphic shows the distribution of female and male participant heights at different times in the study follow-up, presented for the Budesonide and placebo samples.

- An experiment was conducted for better understanding of the effectiveness of a particular type of drug for reducing bad cholesterol (LDL) level. The purpose of the experiment was to determine whether different dosages used have significant different outcomes in average LDL reduction. Twenty subjects with LDL at around 250 to 300 mg/dL had participated in the study and were randomly divided into four groups. Each group was given a specific level of dosage of the drug each day for one month, with a control group that only provided with placebo. The reduction in LDL was recorded and showed in the following table. Positive number indicates reduction and negative numbers indicates increasing in DLD. Use statistical software to analyze the data and answer the following question.

Xenical is used to block the absorption of dietary fat. The article reported that more than 4000 patients in the U.S. and Europe were randomized to receive Xenical or a placebo in a parallel groups study. After one year, 57% of those receiving Xenical had lost at least 5% of their body weight, as opposed to 31% of those receiving a placebo. Assume that exactly 4000 patients were in the study, and that 2000 were randomized to receive a placebo and 2000 received Xenical. Please Compute a 95% confidence interval for the “relative risk” of losing at least 5% of body weight for those receiving Xenical relative to those receiving placebo. Can the drug be considered effective?arrow_forward

After the second dose, 68 of 551 of the subjects in the control group (group 2) experienced drowsiness as a side effect.

After consideration of several designs for the workstation, three specific alternatives are selected as having the best potential for reducing controller stress.

A randomized block design is used to test the hypothesis of no difference in stress levels for the three workstation alternatives.

To study the effects of this ban on smoking behaviors, subjects were randomly selected from two different populations: those from hospitals with the ban and those from hospitals without the ban. Investigators were interested in determining if this smoking ban had any impact on the proportion of smokers employed at each hospital that then quit smoking. Among 843 smoking employees of hospitals with the smoking ban, 56 quit smoking during the study period. Among 703 smoking employees from workplaces without the smoking ban, 27 quit smoking during the study period. Below is the Stata output that was run to determine if there was a statistically significant difference between these two proportions at the α=0.05 level. A.

The study was blind ---those in the study did not know whether they were taking aspirin or a placebo. Of the 11,034 physicians taking a placebo, 189 suffered heart attacks over the course of the study, whereas of the 11,037 taking aspirin, 104 had heart attacks.
