Limited research funding, infrastructure constraints, ethical review complexities, data collection challenges, and publication barriers contrast with rich clinical case diversity, unique disease presentations, public health challenges, and opportunities for impactful research addressing Nigerian healthcare priorities.
Nigerian Medical Education System:
Nigeria’s medical education system includes federal, state, and private medical schools including University of Ibadan College of Medicine, University of Lagos College of Medicine, Ahmadu Bello University College of Medicine, Obafemi Awolowo University College of Health Sciences, and dozens of others. Each institution maintains specific research requirements, but common standards include mandatory research projects for undergraduate MBBS degrees, dissertations for postgraduate fellowship programs, and theses for master’s and doctoral degrees in medical sciences.
Research Requirements by Level:
- Undergraduate (MBBS): Research projects typically in final year, involving case reports, clinical audits, or small studies culminating in project reports or presentations
- Postgraduate Fellowship (Part 2): Dissertation requirements for Nigerian fellowship programs (FWACP, FMCP, FWACS) involving original clinical or epidemiological research
- Master’s Programs: MSc in Public Health, Epidemiology, Clinical Medicine requiring comprehensive theses demonstrating research competence
- Doctoral Programs: PhD in Medical Sciences, Anatomy, Physiology, Pharmacology requiring substantial original contributions advancing medical knowledge
Medical Research Paper Structure and Components
Medical research papers follow standardized structures facilitating systematic communication of research findings while enabling critical evaluation by peers, reviewers, and clinicians.
IMRAD Format:
Most medical research papers use IMRAD structure: Introduction, Methods, Results, and Discussion, preceded by Title, Abstract, and Keywords, and followed by References, Acknowledgments, and Appendices.
Title Selection:
Effective medical research titles concisely communicate study topics, populations, and designs. Nigerian medical titles should specify local contexts when relevant: “Prevalence of Hypertension Among Adult Patients Attending General Outpatient Clinics in Lagos, Nigeria” rather than generic “Hypertension Prevalence Study.”
Abstract Components:
Medical abstracts typically include: Background/Objectives (1-2 sentences), Methods (2-3 sentences describing study design, setting, participants, interventions, and measurements), Results (2-3 sentences presenting key findings with specific data), and Conclusions (1-2 sentences stating main conclusions and implications). Word limits typically range 150-300 words depending on journal or institutional requirements.
Introduction Section:
Introductions establish research context through: problem statement identifying knowledge gaps or clinical challenges; literature review summarizing relevant previous research; study rationale explaining why research is needed; and objectives/hypotheses clearly stating research aims. Nigerian medical introductions should reference Nigerian epidemiological data, local disease burdens, and healthcare system contexts when relevant.
Methods Section:
Methods sections provide sufficient detail enabling study replication, including:
- Study Design: Clearly identify design type (cross-sectional, case-control, cohort, randomized controlled trial, systematic review, etc.)
- Study Setting: Describe location, institution, and relevant contextual factors (e.g., “tertiary referral hospital in Southwestern Nigeria”)
- Study Population: Define inclusion/exclusion criteria, sampling method, and sample size calculation
- Data Collection: Describe instruments, procedures, and timing
- Variables and Measurements: Define all variables, measurement methods, and operational definitions
- Statistical Analysis: Specify statistical tests, software used, and significance levels
- Ethical Considerations: Document ethical approval, informed consent procedures, and data protection measures
Results Section:
Results present findings objectively without interpretation, using:
- Text: Narrative description of key findings
- Tables: Organized data presentation (demographics, comparative statistics)
- Figures: Graphs, charts, or images illustrating findings
- Statistics: Report specific values (p-values, confidence intervals, effect sizes)
Nigerian medical results should present local data transparently, acknowledging Nigerian-specific factors affecting findings like healthcare access, socioeconomic variables, or cultural practices.
Discussion Section:
Discussions interpret findings through:
- Summary of Key Findings: Restate main results
- Comparison with Literature: Relate findings to previous research, explaining agreements and discrepancies
- Mechanisms and Implications: Discuss biological/clinical explanations for findings
- Nigerian Context: Address findings’ relevance to Nigerian healthcare, considering local disease patterns, treatment availability, healthcare infrastructure, and cultural factors
- Limitations: Acknowledge study weaknesses honestly
- Recommendations: Suggest clinical implications, policy recommendations, or future research needs
- Conclusions: Summarize main messages without overstating implications
Medical Citation Styles for Nigerian Students
Medical writing employs several standard citation styles, each with specific formatting rules for in-text citations and reference lists.
Vancouver Style (Numbered Citations):
Vancouver style, widely used in medical journals and preferred by many Nigerian medical schools, uses numbered citations in order of first appearance. In-text citations appear as superscript numbers, and references list numerically.
Example In-Text: “Hypertension prevalence in Nigeria ranges from 20-30% in urban populations.^1,2^”
Example Reference:
- Adeloye D, Basquill C. Estimating the prevalence and awareness rates of hypertension in Africa: a systematic analysis. PLoS One. 2014;9(8):e104300.
AMA Style (American Medical Association):
Similar to Vancouver but with slight formatting differences in reference lists. Used by some Nigerian medical programs and American medical journals.
Harvard Style (Author-Date):
Some Nigerian public health programs and social medicine departments prefer Harvard style using author-date in-text citations: (Adeloye and Basquill 2014).
Citation Management:
Nigerian medical students should use citation management software:
- Mendeley: Free, user-friendly, good for collaboration
- Zotero: Open-source, excellent browser integration
- EndNote: Professional standard, requires purchase or institutional access
- RefWorks: Web-based, often provided by university libraries
Research Methodology in Nigerian Medical Research
Selecting appropriate research methodology represents critical decisions impacting study validity, feasibility, and contribution to medical knowledge.
Study Design Selection:
Cross-Sectional Studies: Assess prevalence of diseases or risk factors at single time points. Common in Nigerian medical research due to feasibility and cost-effectiveness. Suitable for prevalence studies, healthcare utilization research, or knowledge/attitude/practice surveys.
Case-Control Studies: Compare patients with conditions (cases) to those without (controls) to identify risk factors. Useful for studying rare diseases or outcomes in Nigerian contexts where prospective studies prove challenging.
Cohort Studies: Follow populations over time assessing outcome development. Less common in Nigerian medical research due to resource requirements but valuable for establishing causality and temporal relationships.
Randomized Controlled Trials (RCTs): Gold standard for evaluating interventions. Limited in Nigeria due to funding, ethical complexities, and infrastructure requirements, but essential for treatment efficacy research.
Systematic Reviews/Meta-Analyses: Synthesize existing research evidence. Increasingly popular among Nigerian medical students as they require no primary data collection while contributing valuable evidence syntheses.
Qualitative Research: Explores experiences, perceptions, and behaviors through interviews or focus groups. Valuable for understanding healthcare-seeking behaviors, traditional medicine use, or patient experiences in Nigerian contexts.
Data Collection Challenges in Nigeria:
Nigerian medical researchers face specific data collection challenges including:
- Record Keeping: Incomplete medical records in many Nigerian hospitals complicate retrospective studies
- Patient Follow-up: Difficulty tracking patients for longitudinal studies due to mobile populations and limited contact infrastructure
- Laboratory Capacity: Limited laboratory facilities may constrain biomarker studies
