- Which of the following statements BEST describes the concept of contamination in a randomized control trial? Question 6 options: The intervention group is exposed to treatments received by the control group The intervention group receives an intervention other than the intervention being implemented The control group is exposed to the treatment received by the intervention group The control group receives an intervention other than the intervention being implementedThe α level in the context of reporting findings from a randomized controlled trial corresponds to the probability of concluding: Correctly that the treatment and control groups differ with respect to risk of outcome. That the treatment and control groups differ with respect to outcome when in fact they do not. Correctly that the treatment and control groups do not differ with respect to outcome. That the treatment and control groups do not differ with respect to outcome when in fact they do. That you don’t have sufficient information to present results.what are the short comings of randomized clinical trials ?
- When randomizing people to the intervention v. control group in the context of a randomized controlled trial, you should: Choose to enroll the people who are most likely to comply with your study protocol into the intervention group to avoid the problem of people not following through with the prescribed treatment you wish to study and thus lowering your chances of detecting an effect. Allow people to give their informed consent to participate in your study after they find out whether they have been randomized to one of the groups (either intervention or control), so that people who have doubts about any potential risks can make an informed choice about their participation after knowing what group they will be in. Make sure that you are aware of which people are in the intervention group and which are in the control group so that you can tailor your research questions to their groups. All of the above None of the above1. 40 OT students were randomized into two groups and 40 nursing students were randomized into two groups. One of the OT groups and one of the nursing groups were given the opportunity to participate in a research project and present their data at an IPE conference. The other group of OT students and nursing students completed their normal course work. At the end of the semester the faculty measured all of their students’ knowledge about research design and confidence presenting information to others. (a) Independent Variable(s): (b) Dependent Variables(s): (c) Research Design: 2. 60 participants with a diagnosis of bulbar type ALS were divided into two groups to work with SLP either 3 times a week for 1 hour or 6 times a week for 2 hours. At the end of the study, all participants completed an assessment of speech quality and swallowing ability. (a) Independent Variable(s): (b) Dependent Variables(s): (c) Research Design:1) What does these results mean as shown in the three graphs and t-tests? 2) Can you explain why these three graphs and t-tests ended up with these results? 2) How could someone improve on this study using the graphs and t-tests? If other scientists did this study is there something to recommend to them? 3) What variables were not considered in the graphs and t-tests that should be?

- A study published in the journal PLoS One (https://doi.org/10.1371/journal.pone.0217796) in 2019 presented results of a GWAS searching for loci impacting the risk of prolonged QRS in Hispanic/Latino people living in the U.S. QRS prolongation has been associated heart failure and cardiovascular mortality. The Manhattan plot below summarizes the results. The significance threshold for this study is shown as a horizontal line at -log₁0 (p-value) ~7.5. The names of candidate genes at each associated locus are shown at the top of the corresponding SNP tower.
