Question:
Select a peer-reviewed journal article that describes an intervention study aimed at preventing a non-communicable disease outcome. Complete the following questions based on the article you select.
Question 1: Provide the reference of the article and describe the following:
(a) the intervention being employed, and how the intervention relates to the hypothesised aetiological mechanism by which the exposure is associated with the outcome, and
(b)the findings of the example article you selected. [30 marks]
Question 2: Summarise the evidence-base that supports (or does not support) the intervention in the article you selected [30 marks]
Consider the following elements for this question:
1.How many studies of the association?
2.What type of intervention studies? Based on what samples, or population-bases?
3.Are findings across these studies consistent and coherent, particularly from studies of similar or more powerful study designs?
4.Are the results plausible in terms of a biological mechanism?
Question 3: Summarise the key methodological limitations in interpreting the
findings described in Question 1, and assess the extent to which the observed
association can be attributed to mechanisms other than the intervention.
Consider the following elements for this question:
1.Is there a temporal relationship between the intervention and the outcome?
2.Is there a strong relationship between the intervention and the outcome?
3.Is there a dose-response relationship between the intervention and the outcome?
4.Is the outcome measure affected by selection and/or measurement bias?
5.Is the intervention group affected by selection and/or measurement bias?
6.Are the results likely to be affected by confounding?
7.Are the results likely to be affected by chance variation?
