Summary of "Scientific Research (5) Narrative Reviews & Systematic Review"

This lecture explains the structure, components, and differences between narrative (mini) reviews and systematic reviews in Scientific Research. It uses examples to illustrate how these types of reviews are organized, what elements they contain, and how researchers approach them.

Main Ideas and Concepts

1. Narrative (Mini) Review Structure and Components

Title: Reflects the specific subject or topic of the review.
Authors and Affiliations: Information about the researchers and their institutions.
Research Summary (Abstract): A concise summary (5-10 sentences) outlining the main topics and headings covered by the review to help readers decide if the research is relevant to their interests.
Keywords: Terms that help the research appear in search engine results.
Introduction: Provides background knowledge and context for readers unfamiliar with the topic.
Main Axes (Sections): The review is divided into several main axes or themes, each focusing on a specific aspect of the topic:
- First Axis: Overview of the subject or preparation methods.
- Second Axis: Characteristics of the subject/material.
- Third Axis: Specific applications of the subject.
Subheadings: Each main axis is broken down into subheadings detailing different methods or research findings.
Use of References: Citations are included to support statements and provide sources.
Summary/Conclusions: Summarizes findings and highlights the best methods or unique characteristics discovered.
Future Aspirations: Suggestions or recommendations for future research directions.
Variability in Style: While all reviews include these elements, the style and number of references can vary widely depending on the research topic and scope.

2. Systematic Review Structure and Characteristics

Systematic Approach: Unlike narrative reviews, systematic reviews follow a strict, methodical process to collect and analyze all relevant studies on a specific question.
Search Strategy:
- Use of predefined questions or criteria.
- Identification of databases and search engines.
- Number of studies found and screening process to select relevant studies.
Data Extraction and Classification: Each study is analyzed, classified, and summarized systematically.
Use of Tables and Figures: Results are often presented in tables to compare findings across studies.
Strong Discussion Section: Provides an in-depth analysis and comparison of results, often including Meta-analysis or statistical synthesis.
Conclusions and Recommendations: Drawn from the comprehensive analysis.
Keywords and References: Similar to narrative reviews but usually more extensive due to the larger number of studies included.
Transparency and Reproducibility: Emphasis on clear methodology and replicable search strategies.

Detailed Methodology / Instructions for Conducting Reviews

Narrative Review (Mini-Review)

Choose a specific subject/topic.
Collect and summarize existing research related to:
- Preparation methods.
- Characteristics of the subject.
- Specific applications.
Organize content into main axes and subheadings.
Include a clear introduction to provide background.
Write a concise summary highlighting key points.
List keywords for searchability.
Cite relevant references.
Conclude with findings and suggest future research directions.

Systematic Review

Define a clear research question.
Develop a Search Strategy including:
- Search engines/databases to use.
- Keywords and inclusion/exclusion criteria.
Conduct a comprehensive literature search.
Screen and select studies based on criteria.
Extract data systematically from selected studies.
Organize data into tables or charts for comparison.
Perform detailed analysis and discussion of findings.
Conclude with evidence-based recommendations.
Provide keywords and extensive references.
Ensure methodology transparency for reproducibility.

Differences Highlighted Between Narrative and Systematic Reviews

Narrative Review: More flexible, descriptive, and thematic; focuses on summarizing and discussing research in a structured but less rigid way.
Systematic Review: Highly structured, follows a reproducible method; aims to minimize bias by comprehensive and systematic data collection and analysis.

Speakers / Sources Featured

The lecture appears to be delivered by a single instructor or presenter (unnamed).
References to various researchers and research groups (e.g., "Vital D" research group, unspecified COVID-19 related researchers) are mentioned as examples but not directly featured.

Conclusion

The lecture provides a comprehensive overview of how narrative and systematic reviews are structured, highlighting their components, methodologies, and differences. It emphasizes the importance of clarity, organization, and systematic approaches in Scientific Research reviews.
