Required Structured Abstract
Background Context and significance of the health problem
Objective Purpose or research objective
Methods Design, participants/data, and analytical approach
Results Principal findings
Conclusion Main conclusion and implication

8. Keywords

Provide a maximum of five keywords that accurately represent the principal concepts, population, exposure, intervention, outcome, discipline, or health issue addressed by the manuscript.

Keywords must be separated by commas and should facilitate article discoverability in scholarly databases and search services.

9. Introduction

The Introduction should establish the health problem and explain its epidemiological, clinical, public-health, behavioral, social, or health-system context as appropriate. Authors should identify the affected population and setting, explain the significance or burden of the problem, summarize current evidence or recommended practice, and demonstrate the practical importance of the study.

The Introduction should clearly identify:
  • Research background and health problem.
  • Relevant population and setting.
  • Current scientific evidence.
  • Research gap.
  • Novelty or contribution.
  • Research objective, question, or hypothesis.
  • Potential contribution to health science, practice, services, policy, management, or technology.

10. Literature Review

The Literature Review must critically synthesize relevant peer-reviewed health-science research and authoritative scientific sources. Authors should organize the review according to concepts, determinants, mechanisms, interventions, outcomes, theoretical perspectives, methodological approaches, and unresolved health problems rather than merely listing previous authors.

Relevant systematic reviews, clinical or public-health guidelines, epidemiological reports, professional standards, books, datasets, government publications, and institutional reports may be included when scientifically appropriate.

The literature review should explain how previous evidence supports the study framework, variables, intervention, analytical approach, or research propositions.

11. Hypothesis Development

Where applicable, the Hypothesis Development section should translate the identified research gap, theoretical rationale, and empirical evidence into logically derived and testable hypotheses.

Each hypothesis should specify the expected relationship, association, or effect among relevant exposures, determinants, interventions, mediators, moderators, and health outcomes.

Where formal hypotheses are not appropriate, including certain qualitative studies, descriptive studies, case reports, literature reviews, or similar designs, this section may be omitted or adapted to present research propositions or guiding questions.

12. Research Methods

The Research Methods section must provide sufficient methodological detail to support scientific transparency, critical evaluation, and replication where applicable.

Authors should identify and justify the study design, setting, study period, target population, eligibility criteria, sampling strategy, sample-size determination, variables or phenomena, instruments, validity and reliability, interventions or exposures, data collection, quality control, ethical procedures, and analytical methods as appropriate.

Research Methods Framework
Stage 1
Research Question & Design		 Define the research question, objectives, health discipline, population, setting, observation period, variables or phenomena, and appropriate study design.
Stage 2
Population & Sample		 Describe the source population, study population, eligibility criteria, sampling frame, sampling method, sample-size rationale, recruitment, and data sources.
Stage 3
Data Collection & Management		 Describe instruments, clinical measurements, laboratory procedures, interviews, observations, intervention procedures, coding, data entry, and secure data management.
Stage 4
Analysis & Quality Assurance		 Describe statistical, qualitative, or mixed-method analysis and appropriate procedures for quality assurance, uncertainty, bias, and robustness.
Stage 5
Interpretation & Reporting		 Interpret findings in relation to study design, measurement quality, uncertainty, prior evidence, limitations, and implications for health research and practice.

13. Quantitative Research

Quantitative studies should distinguish primary and secondary data, define variables and operational criteria, describe measurement tools and data-quality procedures, and explain sample-size determination and analytical methods.

Where relevant, authors should report model specification, assumptions, effect estimates, confidence intervals, significance thresholds, missing-data handling, confounding, repeated measurements, and sensitivity or robustness analyses.

14. Qualitative and Mixed-Methods Research

Qualitative studies should explain the sampling rationale, researcher position or reflexivity where relevant, data saturation, data collection, coding procedures, theme development, and strategies used to support credibility, dependability, confirmability, and transferability.

Where applicable, authors should describe triangulation, member checking, audit trails, reflexive procedures, and other techniques used to strengthen trustworthiness.

Mixed-method studies should clearly explain both quantitative and qualitative components and how findings are integrated.

15. Ethical Approval

Research involving humans, identifiable health information, biological specimens, clinical interventions, or animals must comply with applicable ethical requirements.

  • State the name of the approving ethics committee or institutional review body.
  • Provide the ethical approval or protocol number where applicable.
  • Describe informed-consent procedures for human participants where applicable.
  • Protect participant and patient privacy and confidentiality.
  • Describe animal research approval and welfare procedures where applicable.

16. Research Instruments and Measurements

Studies using standardized instruments should report the instrument name, scoring procedure, relevant validity and reliability evidence, and any adaptation or translation procedures.

Laboratory and clinical measurements should describe relevant protocols, equipment, measurement units, reference criteria, calibration, and quality-control procedures.

Studies using routinely collected or secondary data should describe extraction, cleaning, linkage, eligibility, and data-quality procedures.

17. Tables and Figures

Tables and figures must be numbered consecutively using Arabic numerals according to the order in which they are first cited in the manuscript.

Element Requirement
Table Title Place above the table
Figure Caption Place below the figure and center it
Numbering Arabic numbering in order of first citation
Source State below adapted or reproduced material
Placement Place near the first citation in the manuscript
Readability Tables, charts, diagrams, and images must remain clear and readable

Tables should contain only essential headings and data and should use horizontal rules without unnecessary vertical lines where possible. Avoid decorative elements and screenshots of tables.

18. Results and Discussion

The Results and Discussion section should present findings logically and explain their clinical, epidemiological, public-health, nursing, midwifery, allied-health, health-system, policy, management, or technological significance as appropriate.

Authors should demonstrate how the findings answer the research question, objective, or hypotheses. Appropriate statistical results, effect estimates, confidence intervals, qualitative themes, or mixed-method findings should be reported according to the study design.

The discussion should compare findings with relevant prior research, explain possible mechanisms and alternative interpretations, discuss implications, and address limitations, bias, uncertainty, generalizability, or transferability.

Authors should avoid merely repeating numerical values already presented in tables or figures. The discussion must provide critical scientific interpretation.

19. Conclusion

The Conclusion should synthesize the principal answer to the research objective or question, state the contribution of the study to health science or practice, and identify the most relevant implication.

Authors should not introduce new data, references, or arguments in the Conclusion. Recommendations for practice, policy, prevention, service improvement, management, technology, or future research should only be included when they follow directly from the findings.
