A qualitative systematic review derives data from observation, interviews, or verbal interactions and focuses on the meanings and interpretations of the participants.

Primary literature includes only original research articles. Narrative reviews, systematic reviews, or meta-analyses are based on original research articles, and hence are considered as secondary sources. Therefore, you should not use these in the data extraction process for your systematic review.
Is systematic review difficult?
However, applying systematic review to complex or open questions remains challenging, and this task is becoming more difficult as the quantity of scientific literature increases.
What is a key characteristic of a systematic review?
The key characteristics of a systematic review are: a clearly defined question with inclusion & exclusion criteria; rigorous & systematic search of the literature; critical appraisal of included studies; data extraction and management; analysis & interpretation of results; and report for publication.

Many reviews did not provide adequate summaries of the included studies. Settings of test use, the expected role of the test, study design characteristics, and demographics of participants, were often not reported. The counts needed to reconstruct the 2×2 tables of results used in each study were often not provided.
What is a good sample size for systematic review?

Systematic reviews always address a specific question. They involve the use of robust methodology to find answers to a clearly formulated question.
What are the strengths of a systematic review?
Again, the potential strength of a systematic review lies in the transparency of each phase of the synthesis process, allowing the reader to focus on the merits of each decision made in compiling the information, rather than a simple contrast of one study to another as sometimes occurs in other types of reviews.

The researchers use an organized method of locating, assembling, and evaluating a body of literature on a particular topic using a set of specific criteria.
Is systematic review a research design?
A systematic review is a high-level overview of primary research on a particular research question that systematically identifies, selects, evaluates, and synthesizes all high quality research evidence relevant to that question in order to answer it.
What is the difference between Cochrane review and systematic review?
A Cochrane review is prepared and maintained using specific methodologies described in the Cochrane Handbook. Systematic reviews of randomised controlled trials provide the clearest evidence for the benefits of a healthcare intervention.
Is ethical approval required for systematic review?
