Individual Case Study

Individual Case Study INSTRUCTIONS

For this assignment, you will be assigned an article from the peer-reviewed literature that describes an epidemiological study. You will use that article to complete aCritically Assessed Study Article Form, in which you will provide a summary of the study by explaining the following:

• Study purpose (This should be a full sentence.  Remember, anytime you use the authors’ words, you must use quotation marks.)
• Study design (What study design that is the focus of this exercise?)
• Describe the source of the data and the study sample
• Primary measure (Sometimes there will be more than 1 primary measure.  However, for the purposes of this assignment, choose just the one that you believe is most important and explain why you made that choice.  Remember that for our purposes, a measure is the construct (such as glycemic control, or depression, or tuberculosis) that we are measuring, NOT the instrument (such as a PDQ-9) or lab test (the HbA1C test) used to measure it.)
• Statistical Test used for the primary measure (It should be Odds Ratio).  (If it is something else, then you need to contact Dr. Tyson.)
• Complete the2×2 table using the data from the study for the primary measure. You will insert the appropriate numbers into the 2×2 table that was used in the study to arrive at the OR reported. (The 2×2 table can be found in the 9th chapter of the textbook, page 254.)
• Calculation using the data from the above table that produced the resulting OR. You will type the numbers from the above table into the formula to show how the resulting OR was derived.  (This formula can be found in the 9th chapter of the textbook on page 253.)
• Interpretation of the measure of association for this case-control/cohort study. You will explain how the above measure of association is interpreted for this case-control or cohort study. The textbook helps you understand how to interpret the OR results.
• Discussion the advantages of using case-control/cohort designs.
• Discussion the limitations of using case-control/cohort designs.
• Discussion of bias (information and selection biases) and confounding for this particular study.
• Description of any methods used in the study for minimizing bias and confounding, or methods that could have been used, but weren’t.

There is an example article and completed form available to you in the Case Study module. You must examine that as a model for the one you will complete for your assigned article. Using this model is the best way for you to understand what is expected of your for this assignment.
