10. Materials and Methods

The Materials and Methods section should provide sufficient detail to enable readers and researchers to understand, evaluate, and, where appropriate, reproduce the study. Authors should describe the study design, setting, participants, data collection methods, interventions, outcome measures, statistical analysis, and ethical considerations in a clear and logical manner.

The methodology should be presented in a chronological sequence and should accurately reflect how the study was conducted.

10.1 Study Design

Authors should clearly describe the study design, such as:

  • Randomized Controlled Trial (RCT)
  • Cohort Study
  • Case-Control Study
  • Cross-Sectional Study
  • Observational Study
  • Case Series
  • Laboratory or Experimental Study
  • Systematic Review and Meta-analysis
  • Qualitative Research
  • Mixed-Methods Study

The study setting, duration, and location should also be clearly stated.

10.2 Study Population

Provide detailed information regarding the study participants, including:

  • Inclusion criteria
  • Exclusion criteria
  • Sample size
  • Sampling technique
  • Recruitment process

Authors should explain how the study population was selected and justify the sample size where appropriate.

10.3 Data Collection

Describe the methods used for data collection, including:

  • Study instruments or questionnaires
  • Laboratory methods
  • Diagnostic criteria
  • Clinical assessments
  • Imaging techniques
  • Follow-up procedures

Validated instruments should be appropriately referenced.

10.4 Outcome Measures

Clearly define the primary and secondary outcome measures evaluated in the study.

Outcome measures should be objective, clearly described, and consistent with the study objectives.

10.5 Statistical Analysis

Authors should provide sufficient information regarding statistical methods, including:

  • Statistical software used (including version)
  • Statistical tests performed
  • Level of statistical significance (e.g., p < 0.05)
  • Confidence intervals (where applicable)
  • Handling of missing data
  • Adjustment for confounding variables (if applicable)

The statistical analysis should be appropriate for the study design and research objectives.

10.6 Ethical Considerations

Studies involving human participants or human data must have prior approval from a recognized Institutional Review Board (IRB) or Ethics Committee.

Authors should include:

  • Name of the approving institution
  • Approval/reference number
  • Date of approval

Research involving human participants should be conducted in accordance with internationally accepted ethical principles, including the Declaration of Helsinki and applicable national regulations.

10.7 Informed Consent

Where applicable, authors must confirm that written informed consent was obtained from all participants or their legally authorized representatives before enrolment in the study.

For studies involving minors, consent must be obtained from a parent or legal guardian.

10.8 Clinical Trial Registration

Prospective clinical trials should be registered in a publicly accessible clinical trial registry before participant enrolment.

Authors should provide:

  • Registry name
  • Registration number
  • Registration date

10.9 Reporting Guidelines

Authors are encouraged to prepare manuscripts according to internationally recognized reporting guidelines, including:

  • CONSORT
  • PRISMA
  • STROBE
  • CARE
  • STARD
  • ARRIVE

Completed reporting checklists should be submitted as supplementary files where applicable.

10.10 Reproducibility and Transparency

Authors should provide sufficient methodological detail to allow independent researchers to replicate the study.

Where appropriate, authors are encouraged to provide information regarding:

  • Data availability
  • Study protocol
  • Analytical methods
  • Software used
  • Supplementary materials

Notes

  • All methods should be described in sufficient detail to ensure transparency and reproducibility.
  • Previously published methods should be appropriately cited instead of reproduced in full.
  • Any modifications to established methods should be clearly explained and justified.
  • Proprietary products, instruments, or software should be identified by their generic name, manufacturer, city, and country where appropriate.
