What is a systematic review?

• A rigorous summary of all primary research

evidence relevant to a focused question.

• Evidence is consolidated through a systematic

process to avoid possible sources bias at

various stages in the review process. – (Haynes, 2007)

Anatomy of a systematic review

• Abstract

• Introduction

• Methods

• Results

• Discussion

• Conclusion

15


Abstract and Introduction

The abstract provides an overview of what is in

the systematic review.

The introduction stated the review question,

provides background information about the

problem, intervention or population and gives the

rationale for the question.

16


Methods

The methods section describes how the

systematic review was conducted. This section

includes information about the criteria for including

or excluding studies; how the search for studies

was conducted; how the primary studies were

assessed for quality and by whom; and how data

from the included studies were extracted,

analyzed and synthesized.

17


Results

The results section summarizes the findings

reported in the individual studies included in the

systematic review, including:

• methodological quality of those studies;

• key characteristics of the studies (e.g.,

demographics of study participants, setting,

sample sizes, interventions,

intervention comparisons, risk of bias); and

• effect of the interventions on outcomes.

activity among socioeconomically disadvantaged women: A systematic review and meta-analysis. Obesity Reviews,

14(3), 197-212.

19


Discussion and conclusion

The discussion section summarizes the main results of the review, compares the findings of the

review to existing literature, and states limitations of the review. The discussion section also includes the author’s interpretation of the results and their implications for policy, practice and future research.

The conclusion summarizes recommendations for policy, practice and future research.

Critical appraisal

The process of systematically examining research

to judge its trustworthiness, and its value and

relevance in a particular context.
