Hi Maria,
Can you please provide written instructions for our final assignment? We discussed it in lecture verbally on May 8th, but I don't see written instructions on any of the slides. Would be helpful to have them to make sure the assignment is completed thoroughly.
Thank you,
-Luis
I found that in the announcement section:
Final research project write-up:
Read recent issues of a journal in your field (e.g., Am J Epi; Epidemiology; Neurology; Pediatrics). Choose an article that addresses a research topic of interest to you using an observational study design. Summarize the study design, sampling, and analytic plan used in the paper. Draw a DAG corresponding with the author’s implicit or explicit causal hypotheses and specify which part of the DAG they are testing in this article. Review their handling of statistical conclusion validity, internal validity and external validity. Describe what you consider the greatest weaknesses of the paper. (This should be ~2000 words).
Write the methods section for an alternative study that would address the same research topic with either a stronger design or a design that addressed the most important limitations of the initial study. This should be ~1500-2000 words.
Have fun
Just to add that the alternative study design should preferably not be an RCT
Thank you, Francois and Maricianah.
Luis
