    • Choose the article that you will use for the final project, and share on the forum. Due Thurs, April 22 by 8 pm. 

      Final research project write-up (from the Syllabus):

      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. 

      1. 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.)

      2. 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.)
