• Results
• Discussion

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.
