What were the sampling exclusion criteria for the Zeiger et al. (2005) study?
Why do you think that the researchers screened 901 patients for their study?
Of the 400 subjects randomized to the two treatment groups, what number of participants were discontinued from the study due to a drug packaging error resulting in incorrect study medications? This resulted in what mortality race for the study?
Of the 191 subjects in the fluticasone treatment group, 151 completed the open-label therapy. How many subjects dropped out of this group, and what was the mortality rate from this group during the study? Round your answer to the nearest whole percentage.
Discuss the mortality rate in Question 4. Did this mortality rate have a potential effect on the results of this study? Provide a rationale for your answer.
The researchers acknowledged that 901 potential subjects were screened and 401 did not meet sample criteria, leaving 500 subjects to be approached for inclusion in this study. Of the 500 potential subjects, 100 were not randomized into groups for "Other" reasons. Assuming that these 100 potential subjects refused to participate in the study, what is the refusal rate for this study? Round your answer to the nearest whole percentage.
Do you think that it would have been helpful if the researchers had discussed reasons for refusal? Provide a rationale for your answer.
What reasons for sample mortality were provided for this study?
Did the sample size provide enough power co correctly reject the null hypothesis with regard to rescue-free days during the double-blind period? Provide a rationale for your answer.
Why do you think that it is important for pharmaceutical or drug studies, such as this one, to have a large sample?
