Appendix
Purpose of this appendix
This section provides practical tools to apply the framework in real-world clinical evaluations.
These are not rigid templates.
They are:
👉 structured aids to support consistent reasoning
Clinical Evaluation Checklist
Use this as a high-level review tool.
Evidence and Intended Use
- Is the intended purpose clearly defined?
- Is the intended use explicitly described?
- Is the target population specified?
- Is the evidence aligned with intended use?
Study Appraisal
- Are study designs appropriate?
- Are populations relevant?
- Are endpoints clinically meaningful?
- Are methods appropriate?
Bias and Limitations
- Are potential biases identified?
- Are limitations clearly stated?
- Is uncertainty acknowledged?
Risk–Benefit Evaluation
- Are benefits clearly defined?
- Are risks characterized (severity, frequency)?
- Is benefit balanced against risk?
Equivalence and Justification
- Is equivalence appropriately assessed?
- Are similarities and differences analyzed?
- Is justification clearly explained?
Clinical Context and Applicability
- Does the evidence reflect real-world use?
- Are contextual differences addressed?
Synthesis and Interpretation
- Are findings integrated across studies?
- Are inconsistencies addressed?
- Is uncertainty incorporated?
Claims
- Are claims supported by evidence?
- Are claims proportionate to evidence strength?
- Are limitations reflected in claims?
Communication
- Are claims clearly written?
- Is wording precise and unambiguous?
- Is traceability to evidence maintained?
Study Appraisal Worksheet
For each study, document:
- Study design
- Population
- Endpoints
- Sample size
- Key findings
- Strengths
- Limitations
- Potential bias
- Overall reliability
Bias Identification Guide
When reviewing a study, check for:
- Selection bias
- Measurement bias
- Confounding
- Reporting bias
- Attrition bias
Ask:
👉 How could this bias affect the results?
Risk–Benefit Evaluation Template
Benefits
- What benefits are observed?
- How clinically meaningful are they?
Risks
- What risks are identified?
- What is their severity and frequency?
Conclusion
- Does benefit outweigh risk?
- Under what conditions?
Equivalence Assessment Template
- Comparator device or evidence source
- Similarities (technical, clinical, biological)
- Differences
- Impact of differences
- Justification of equivalence
Applicability Check
- Population match
- Clinical setting match
- Use conditions match
- Device usage consistency
👉 If differences exist, assess impact
Synthesis Framework
- Summary of individual studies
- Weight of evidence
- Consistency of findings
- Identified uncertainties
- Overall interpretation
Claim Development Checklist
- What is being claimed?
- What evidence supports it?
- What are the limitations?
- What qualifiers are needed?
- Is wording precise?
Traceability Structure
For each claim, ensure:
- Link to supporting evidence
- Link to evaluation steps
- Clear reasoning path
👉 This enables review and validation
Final Note
These tools are intended to support:
👉 structured, transparent, and defensible clinical evaluation
They should be adapted to:
- device type
- regulatory context
- available evidence
Citation Approach in This Guide
This guide uses citations selectively to support key concepts, not to exhaustively document every statement.
Citations are included where they:
- Anchor formal definitions (for example, clinical evidence, bias, or risk–benefit evaluation)
- Reference established methodological frameworks (such as evidence grading or study appraisal)
- Reflect regulatory expectations relevant to clinical evaluation
The goal is to maintain a clear and readable narrative while ensuring that critical reasoning steps are grounded in recognized standards.
This approach aligns with the purpose of the guide:
to support reproducible reasoning, not just reproducible results.
