Systematic literature review writing AIIMS Bhubaneswar

Systematic literature review writing AIIMS Bhubaneswar. Conducting evidence-based clinical, translational, and public health research at the All India Institute of Medical Sciences (AIIMS), Bhubaneswar demands adherence to international reporting standards, prospective protocol registration, and publication-ready indexing targeting high-impact Q1/Q2 medical journals indexed in PubMed, MEDLINE, and Scopus. Postgraduate MD/MS/DM/MCh scholars, PhD candidates, and clinical faculty face rigorous methodological benchmarks when synthesizing evidence for dissertations, extramural projects, and peer-reviewed journal submissions. Delivering a methodologically sound Systematic literature review writing AIIMS Bhubaneswar bridges tertiary and national healthcare evidence with globally recognized medical scholarship.

Establishing PICO Protocols and PROSPERO Registration

A high-yield systematic review begins with a focused research question constructed via the PICO (Population, Intervention, Comparison, Outcome) or PECO framework. Investigators draft and register prospective review protocols on international registries like PROSPERO or the Open Science Framework (OSF) to establish transparency, prevent duplication, and define an auditable methodological pipeline. Defining unambiguous inclusion and exclusion criteria at inception eliminates post-hoc selection bias.

Multi-Database Search Execution and PRISMA 2020 Compliance

Publishing in top-tier indexed medical journals requires broad, reproducible database search algorithms:

• Formulating structured Boolean syntax combining Medical Subject Headings (MeSH), Emtree terms, and free-text keywords across PubMed, Embase, Cochrane CENTRAL, Scopus, and Web of Science.
• Screening grey literature repositories, trial registries (CTRI, ClinicalTrials.gov), and backward/forward citation tracking to eliminate publication bias.
• Documenting the screening workflow (identification, screening, eligibility, inclusion) via standardized PRISMA 2020 flow diagrams.

Methodological Quality and Risk of Bias Assessment

Systematic appraisal demands domain-specific assessment tools tailored to study designs:

• Randomized Controlled Trials: Assessed using the Cochrane RoB 2 (Risk of Bias 2) tool across all five bias domains.
• Non-Randomized & Observational Studies: Assessed using ROBINS-I (for non-randomized interventions) or the Newcastle-Ottawa Scale (NOS) for case-control and cohort designs.
• Diagnostic Accuracy Studies: Evaluated using the QUADAS-2 framework.
• Certainty of Evidence: Synthesized and reported using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework to generate Summary of Findings (SoF) tables.

Quantitative Data Synthesis and Meta-Analysis

Where studies are sufficiently homogenous, quantitative outcomes are synthesized using dedicated statistical packages:

• Computing pooled effect measures: Risk Ratios (RR), Odds Ratios (OR), Hazard Ratios (HR), Mean Differences (MD), or Standardized Mean Differences (SMD).
• Quantifying inter-study heterogeneity and running random-effects or fixed-effect models.
• Generating publication-quality Forest plots, Subgroup/Meta-regression analyses, and Funnel plots with Egger’s and Begg’s tests to evaluate publication bias and small-study effects.

ICMJE Ethical Standards and Journal Formatting

Final manuscript preparation requires alignment with ICMJE publication ethics, Vancouver/NLM citation standards, structured data extraction tables, and rigorous plagiarism verification (Turnitin/iThenticate) to ensure seamless editorial evaluation and peer review clearance.
