Reflect upon the content of the topics we have covered in this course, and critically appraise the article you have selected by answering the following questions. You may use additional source material as you need to.

The following questions are guide to your essay as these points should be addressed. These are all epidemiological concepts that we covered in the course but you are free to arrange them differently under sub-heading or stick to question answer format if you find it difficult.     

 

QUESTION 1:

Describe the evidence presented in the paper you selected. Specifically address the following questions:

-What is the issue addressed in the paper?

- What was the exposure or intervention?

-What was the outcome?

-What was the study design?

-What was the study population?

-What were the main findings?

QUESTION 2:

Do you think there is evidence of a causal association between the exposure and the outcome? This question relates to the internal validity of the study. Consider the following questions in your critique:

-Is there a temporal relationship between exposure and outcome?

-Is there a strong relationship between the exposure and the outcome?

-Is there a dose-response relationship between exposure and the outcome?

-Are the results consistent within the study?

QUESTION 3:

To what extent can the observed association between the exposure and outcome be attributed to non-causal explanations? Consider the following questions in your critique:

-Are the results likely to be affected by selection and/or measurement bias?

-Are the results likely to be affected by confounding?

-Are the results likely to be affected by chance variation?

QUESTION 4:

Do the findings accord with other evidence? Specifically:

-Are the findings consistent with other evidence, particularly evidence from studies of similar or more powerful study design?

-Are the results plausible in terms of a biological mechanism?

QUESTION 5:

Are the findings externally valid, that is generalisable? Specifically:

-Can the findings be applied to the source population from which the study population was derived?

-Can the study results be applied to other relevant populations?

I have tried other sites for assignment help but the result that Insta Research has produced outweighs others. Since I am weak at writing and shaping the data logically, I am glad I took help from this site. Thanks to my writer for such a great quality of the assignment in Business.
