Comprehensive frameworks for planning, conducting, and synthesizing literature reviews across academic and professional research contexts.

Review Types

Type	Purpose	Scope	Methodology Rigor	Best For
Narrative	Broad overview of a topic	Wide, flexible	Low-Medium	Background sections, introductions
Systematic	Answer a specific research question	Narrow, predefined	High	Evidence-based decisions, clinical practice
Scoping	Map available evidence on a topic	Wide, structured	Medium	Emerging fields, identifying gaps
Meta-Analysis	Quantitative synthesis of findings	Narrow, statistical	Highest	Combining effect sizes, treatment efficacy
Rapid

Do you need to answer a specific, focused question?
  YES --> Is quantitative synthesis of effect sizes needed?
    YES --> Meta-Analysis
    NO  --> Systematic Review
  NO --> Do you need to map the breadth of evidence?
    YES --> Is the field well-established?
      YES --> Umbrella Review (review of reviews)
      NO  --> Scoping Review
    NO --> Do you need to combine qualitative and quantitative?
      YES --> Integrative Review
      NO --> Is time constrained (< 3 months)?
        YES --> Rapid Review
        NO  --> Narrative Review

BUILDING A SEARCH STRING:

Step 1: Identify key concepts from PICO/PEO
  Concept 1: "telemedicine" OR "telehealth" OR "remote consultation" OR "virtual care"
  Concept 2: "diabetes" OR "type 2 diabetes" OR "T2DM" OR "diabetes mellitus"
  Concept 3: "glycemic control" OR "HbA1c" OR "blood glucose" OR "patient outcomes"

Step 2: Combine with Boolean operators
  (Concept 1) AND (Concept 2) AND (Concept 3)

Step 3: Apply filters
  - Date range: 2015-2025
  - Language: English
  - Study type: RCT, cohort, systematic review
  - Peer-reviewed only

ADVANCED OPERATORS:
  "exact phrase"      - Exact match
  *                   - Truncation (therap* = therapy, therapies, therapeutic)
  MeSH terms          - Controlled vocabulary (PubMed)
  NEAR/3              - Proximity (terms within 3 words)
  ti,ab               - Title and abstract search

3. DEVELOP: Generate analytical themes that go beyond the primary studies
4. MAP: Create a thematic map showing relationships between themes
5. WRITE: Narrate findings organized by analytical themes

THEMATIC MAP STRUCTURE:

  |-- Sub-theme 1
  |   |-- Code A (Studies 1, 3, 7)
  |   |-- Code B (Studies 2, 5)
  |-- Sub-theme 2
  |   |-- Code C (Studies 1, 4, 6)

Pitfall	Description	Prevention
Cherry-picking	Selecting only studies that support a hypothesis	Pre-register protocol, follow PRISMA
Narrative bias	Describing studies without critical analysis	Use appraisal tools, compare across studies
Scope creep	Expanding focus beyond original question	Stick to predefined inclusion criteria
Recency bias	Over-weighting recent studies	Include full date range, weight by quality
Publication bias	Missing grey literature and null results	Search preprints, dissertations, trial registries
Inadequate search	Too few databases or narrow search terms	Minimum 3 databases, iterative search refinement
Poor synthesis	Listing studies instead of integrating findings	Use synthesis frameworks, identify patterns
Missing protocol	No pre-registered review protocol	Register on PROSPERO or OSF before starting
