Task 2: Written Assessment
Critical appraisal of an epidemiological paper.
A paper for critical appraisal will be provided to you. The title, abstract, most of the discussion and some parts of the paper will be redacted.

lecture to frame your critical appraisal. Your critical appraisal should cover design, study population, errors, confounding, study findings and
interpretation and your conclusions about the study.
