Types of Literature Review That We Offer

At Pubrica, we provide a wide range of literature review and research gap analysis formats tailored to meet the unique objectives of researchers, clinicians, and academic writers. Our experts are skilled in producing both qualitative and quantitative reviews across multiple domains.

State of the Art Review

This review offers a critical and current perspective on the most advanced developments in a specific research area. It highlights cutting-edge trends, technologies, and gaps needing further exploration.

Narrative Literature Review

This review provides a descriptive and interpretive summary of the literature on a broad topic. It is flexible in scope and useful for understanding historical development, theoretical context, or scholarly debates.

Scoping Review

A scoping review maps the existing literature on a specific topic or research area. It identifies key concepts, knowledge gaps, and types of evidence available without assessing study quality.

Cochrane Reviews

A kind of systematic review that is ideal for creating reliable information produced under strict adherence.

Rapid Reviews

Conducted in a shorter timeframe. Applied for creating timely evidence in response to urgent decision-making healthcare policy or practice needs. This method perfectly balances quality and deadline.

Umbrella Reviews

Summary of the results of previous systematic reviews that provides a general overview of the evidence on a particular subject or topic.

Meta Analysis

Integrating and interpreting qualitative research results to provide new understandings, hypotheses, or insights beyond the findings of individual studies

Integration Review

An integration review synthesizes past empirical and theoretical literature to provide a holistic overview of a topic. It identifies patterns, contradictions, and emerging themes across diverse studies.

Conceptual Review

A conceptual review explores key theories, models, and frameworks that shape a field of study. It aims to refine existing concepts or propose new theoretical directions.

Expert Review

Conducted by subject matter experts, this review evaluates literature through a highly informed lens. It emphasizes accuracy, depth, and practical insights grounded in extensive field knowledge.

Scholarly Review

A scholarly review critically assesses peer-reviewed literature with an academic approach. It ensures methodological rigor and scholarly depth suitable for academic writing services, publication, or thesis support.

Research Review

This type examines empirical studies to evaluate research designs, outcomes, and quality. It helps identify methodological strengths, limitations, and evidence gaps in existing research.

Literature Review for Regulatory Submissions

This review compiles and evaluates scientific literature required for submissions to regulatory authorities. It ensures compliance, supports safety and efficacy claims, and strengthens the documentation process.

Targeted Literature Review (TLR)

A Targeted Literature Review focuses on a narrowly defined research question or population. It is often used in clinical or policy settings to gather relevant data quickly and efficiently.

Systematic Literature Review (SLR)

A Systematic Literature Review uses a structured, predefined protocol to identify, appraise, and synthesize all relevant studies on a specific topic. It ensures transparency, reproducibility, and minimizes bias in summarizing existing evidence.
