Q & A

What are the seven steps for writing a systematic review?

The seven steps for writing a systematic review are: 1) Define the research question, 2) Develop the review protocol, 3) Conduct the search, 4) Screen the studies, 5) Assess the quality of the papers, 6) Extract data and synthesize, and 7) Present your findings.

What is the Pico framework and how is it used?

The Pico framework is a tool used to define a research question. It stands for Population, Intervention, Comparison, and Outcome. It helps to structure the research question by identifying the specific group of people (population), the intervention being studied, the comparison group or condition, and the outcome or effect that is being measured.

How does the Pico framework differ for qualitative research?

For qualitative research, the Pico framework changes slightly, with the 'O' representing 'context' instead of 'outcome'. This allows for a focus on the setting or circumstances in which the research is conducted.

What is the purpose of developing a review protocol?

The purpose of developing a review protocol is to outline the exact method for searching through databases to find relevant papers and literature that will help answer the research question. It includes data extraction, limitations, exclusion and inclusion criteria, and other important aspects of the search methodology.

What are some strategies for identifying keywords for a systematic review search?

Strategies for identifying keywords include brainstorming, using a thesis, utilizing search engines, and using tools like WordFreak which analyzes a library of papers to identify the most commonly used words.

Why is it important to record the search limits used during a systematic review search?

Recording the search limits is important because it documents the scope of the search and ensures transparency in the search process. This information is crucial for replicating the search or for understanding why certain papers were included or excluded.

What is the Methods Wizard tool and how does it assist in the systematic review process?

The Methods Wizard is an AI tool that helps in systematically inputting and organizing the details of the methods section for a systematic review. It allows users to input information about study selection, data extraction, analysis, and eligibility criteria, and then generates a complete methods section.

How can gray literature be relevant to a systematic review?

Gray literature, which includes non-peer-reviewed papers, conference proceedings, government reports, and more, can be relevant to a systematic review if it provides important information related to the research question. It needs to be assessed for quality and relevance just like peer-reviewed literature.

What is the PRISMA diagram and how does it help in the systematic review process?

The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) diagram is a flow diagram that visually represents the process of identifying, screening, and selecting studies during a systematic review. It helps to document the number of studies at each stage and provides a clear record of the search process.

How can the risk of bias in studies be assessed during a systematic review?

The risk of bias can be assessed using tools that evaluate the strengths and weaknesses of the studies, as well as potential biases. One such tool mentioned is an AI-based tool that generates a review showing potential biases in the studies included in the systematic review.

What are the key differences between synthesizing data for qualitative and quantitative systematic reviews?

In qualitative systematic reviews, the focus is on generating codes, identifying themes, and understanding the non-numerical data, whereas in quantitative reviews, the focus is on statistical analysis, numbers, and often representing data through methods like forest plots.

What does the systematic review blank template include and how does it help in writing a systematic review?

The systematic review blank template includes sections for abstract, introduction, methods, results, discussion, conclusions, references, and appendices. It helps by providing a structured outline to fill in with the relevant information from the review, ensuring that all necessary components are included and organized.
