Knowledge

Students will:

• have the knowledge they need to search widely for studies for a systematic review, including the choice of sources to search and the words or phrases to use in the search.
• know how to assess the quality of potentially eligible studies and be able to identify suitable tools to use to assess quality and risk of bias.
• understand the basic principles of the meta-analyses techniques used for systematic reviews (including heterogeneity).

Skills

Students will be able to:

• state the research question for a systematic review, to cover key aspects of, for example, the population, interventions or exposures and outcome measures.
• choose the inclusion and exclusion criteria for a systematic review, including the types of participant, types of intervention or exposure (where appropriate) and types of outcome measure.
• set the eligibility criteria.
• plan the data extraction for a systematic review, and to design a simple data extraction form.

Competencies

Students will be able to:

• understand the practical aspects of doing a systematic review.
• use this knowledge to appraise systematic reviews.

Home assignment/multiple choice based on 1-2 systematic review papers. The exam will be graded as passed or not passed.

The assignments may be completed in English.

Work requirements: Participation in lectures.

Students who do not pass the exam will be offered a re-sit exam the following semester.

The date for the exam can be changed. The final date will be announced at your faculty early in May and early in November.
