Question: Find a published research study on a topic that you could use for your DNP project that reported ORs or RRs(NO meta-analysis)

Give the purpose/objective/aim of the study exactly as it is written in the study.
What is the population in the study?
Identify the variables in the study that you will focus on. Designate the variables as an IV and DV. What is the level of measurement of the variables (nominal, ordinal, interval, or ratio), and type (categorical or continuous)? Get professional assignment writing service now!
If one or more hypotheses were stated in the article for the OR or RR, give the one you will focus on here. Give the stated hypothesis as an equation. Write the other hypothesis (the Ho or Ha that was not given) in words and an equation. If a hypothesis was not stated, then restate the purpose/objective/aim as a null hypothesis in words and equation format. Do this for both a null and alternative hypothesis. Again, focus on only two sets of variables tested by an OR or RR. Use the format in the handout attached to the announcement for this week.
What is the assumption for ORs or RRs (cite the source where you find it)? Is it met in this study? Provide information given in the study that can be used to determine whether each assumption is or is not met. What information is not given?
What alpha level (level of significance) was used?
Give the descriptive statistics for at least two risk factors and related outcome(s) analyzed by ORs or RRs.
Give the values for the ORs or RRs and p-value for the risk factors named used for the descriptive statistics.
Use the p-value rule to determine whether to reject or fail to reject the null hypothesis.
What type of error is possible based on the decision about the null hypothesis? List the common reason(s) for this possible error and identify which of them applies to this study.
If CIs are reported for the ORs or RRs, use the CI rule to determine whether to reject or fail to reject the null hypothesis.
Do the risk factors increase or decrease the risk of the outcome or event? Explain your answer.
Convert the OR or RR to a percentage and interpret the magnitude of the OR or RR.
Determine the clinical significance of the ORs or RRs by using your knowledge, critical thinking, and experience with your patients and setting, would you incorporate the variables into your practice, for example, adding them to your assessment in order to identify patients at risk for the outcome or event? Is your evaluation of the clinical significance of the findings consistent with the statistical significance for the findings? Explain your rationale.
