The assessment is a 3,000 word structured critical analysis of published research or
study, which will include a discussion of epidemiologic issues. The objective of the
assessment is to enhance your ability to make sound epidemiologic judgements
related to a public health issue and to give you experience of critically appraising an
epidemiologic and/or public health research article.
Three suggestions are provided below if you are uncertain about which topic area /
study to critically appraise; please choose only one. If you wish to focus on a
different topic area or study, please discuss this with your module tutor first to make
sure it is appropriate.

literature, as well as global health and/or dominant health systems, to demonstrate
the wider reading you have done.
Tables and graphs can be used where applicable to maximum advantage to
summarize the features, results, and peculiarities/limitations of the studies being
reviewed. Please ensure all tables and graphs are referenced and titled. The text
