Based on epidemiology knowledge and critical thinking. You need to describe the methods used in each study and briefly describe the advantages and disadvantages of the methods used. I expect you to include a paragraph presenting your conclusion(s) about the topic of your two articles. This concluding paragraph should state what you think based on your two papers- not what the authors have concluded. Include in this paragraph: • Is there or is there not an association? • Could the relationship be considered causal?

I expect you to include a paragraph presenting your conclusion(s) about the topic of your two articles. This concluding paragraph should state what you think based on your two papers- not what the authors have concluded. Include in this paragraph:
• Is there or is there not an association?
• Could the relationship be considered causal?
• What data would it take to convince you that there is an association?
• Would you use a different study design, measurement, or control for some other confounders?
