Ethics & Informed Consent: Systematic Review & Meta-Analysis (Portugal)

1. Ethical Principles & Legislative Framework

In research involving human participants, securing ethical clearance is a critical first step. For a Systematic Review & Meta-Analysis being conducted in Portugal, study designs must align with the primary regulatory legislation: Clinical Research Act (Law 21/2014). This statutory framework ensures participant welfare, confidentiality, and voluntary involvement are protected.

Administrative review and formal approval are managed by a local or regional Comissão de Ética para a Investigação Clínica (CEIC). Researchers must secure full approval or a formal exemption certificate from this board before recruiting any participants or commencing data collection.

2. Study Design Elements & Reporting Integrity

For a Systematic Review & Meta-Analysis, the review board places significant focus on methodological transparency. The application must outline the research rationale, recruitment protocols, inclusion and exclusion criteria, and data protection measures.

Study Classification: Exempt (No Human Participant Recruitment)

Meta-analyses rely on previously published scholarly studies. The project does not recruit active subjects, making it exempt from direct human ethics board audits.

To guarantee academic integrity and reproducibility, the study report and subsequent publications should follow the internationally recognised reporting standard: PRISMA declaration.

3. Informed Consent & Information Sheet Guidelines

A robust participant information sheet and informed consent form are critical parts of the ethical application. Ensure your documentation incorporates the following components:

• Plain Language Explanations: Avoid complex medical or technical terminology. Ensure readability matches the general population.
• Voluntary Participation: Explicitly state that participation is entirely voluntary and that individuals can withdraw at any time without negative consequences.
• Confidentiality & Data Controls: Explain how participant data will be anonymised or pseudonymised, who will have access to it, and how long it will be securely retained under EU GDPR & Portuguese Data Protection Act (Law 58/2019).
• Risk/Benefit Disclosure: Clearly list any potential risks, discomforts, or direct benefits associated with participation in the study.
• Ethics Board Contact Information: Provide the contact details of the reviewing Comissão de Ética para a Investigação Clínica (CEIC) so participants can reach out if they have questions or concerns.

Research Ethics, Clinical Trials & Institutional Governance

The study protocol aligns with the spirit of the Declaration of Helsinki ethical principles by verifying original trials' ethical status. While secondary reviews do not replicate historical abuses like the Tuskegee syphilis study ethics infractions, sourcing must be validated. The study design is exempt from direct application of the ethical principles of informed consent as it utilizes published data. Though researchers must have basic human subjects research training, they are exempt from standard continuing review irb cycles. Registering the study protocol with the library ensures compliance to secure formal research ethics approval from the university. Ethical oversight committees in Portugal audit the study's consent registry periodically to verify compliance with national legal statutes.
