1) Overview of the paper you selected.
-What is the issue addressed in the paper, is it important novel?
– 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? Were the authors advise for future direction or about the study implication

2) Appraise the internal validity –
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 biases including confounding,
-Are the results likely to be affected by chance variation? Are they clearly presented

3) Do you believe a causal association between exposure and outcome is plausible? Is the finding within the study consistent – has any interaction or special mechanism was illustrated/suggested

4) Appraise the external validity of the finding and the overall quality of the discussion section, -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?
