- The 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.I am stuck on four questions for this lab and they are: 1. What is the question being investigated in this experiment. 2.

- Match the following study types to their definition below: case control study, randomized controlled trial, registry, Inv estigational Device Exemptions (IDE) Prospectively comparing the outcomes of patients randomly assigned to be treated with a new device or procedure relative to a control group that may receive no treatment or standard treatment A. Case control study Monitoring outcomes through a collection of cases performed in a real world, which may be accumulated either prospectively or retrospectively after a number of cases have been performed B. Registry - ~ Retrospectively comparing the outcomes of a group of patients treated with a new device or procedure to a matched group receiving no treatment or a standard treatment C. Investigational Device Exemptions (IDE) - ~ Allows a device to be used in a clinical study in order to collect safety and effectiveness data. D. Randomized controlled trialWhen 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 aboveScreening test A as a sensitivity of 78% and a specificity of 85%. Screening test B has a sensitivity of 85% and a specificity of 90%. Given that they are applied to the same population and the same disease, which of the following statement is correct? Screening test A has a higher yield than Screening test B Screening test A is more valid than Screening test B Screening test B has better predictability than Screening test A Screening test B is more valid than Screening test A Screening test A has better predictability than Screening test B
