Calibrated trust hinges on case-level transparency: clinicians need both the score and context about how much to trust it for this patient.

1. Relevant knowledge points and concepts
- Trust calibration: users should neither over-rely (automation bias) nor underuse (distrust) an AI. Appropriate calibration requires actionable output plus uncertainty and scope information.
- Explainability: concise, clinically relevant reasons (key contributing factors) help clinicians evaluate plausibility.
- Intended use and reliability warnings: knowing whether a case falls inside the model’s training distribution and any case-specific data limitations affects how much weight to place on the alert.
- Human-AI workflow: information must be presented before action so clinicians can integrate it into decision-making.

2. Step-by-step reasoning
- Step 1: Clinician receives a risk score. Alone, a number invites either blind acceptance or dismissal.
- Step 2: Providing key contributing factors lets the clinician check concordance with clinical findings (face validity).
- Step 3: Indicating whether the case is within intended use signals if model behavior is likely reliable for this patient.
- Step 4: Case-specific reliability warnings (e.g., missing vitals, unusual comorbidity profile) explain increased uncertainty.
- Step 5: Presenting these elements before action enables clinicians to weight the alert appropriately and decide next steps.

3. Calculations
- No numeric calculations required; the argument is conceptual and workflow-focused.

4. Why the correct answer is correct
- Showing the score, contributors, intended-use flag, and case-specific reliability warnings directly equips clinicians to judge both the signal and its uncertainty, which is the essence of calibrated trust.

5. Why other options are incorrect
- Option 2: Performance summaries and identical displays lack per-case applicability and intended-use flags; they don’t indicate when the model may be unreliable for a specific patient.
- Option 3: A “clinically reviewed” badge and overall accuracy can create false reassurance and conceal case-level limitations.
- Option 4: Mandatory accept/override and post-hoc monitoring aids governance but does not proactively give clinicians the contextual reliability information needed to calibrate trust before acting.

6. Conclusion
The best design is to show the risk score with key contributing factors, whether the alert is within the tool’s intended use, and any case-specific reliability warnings before physicians act on the alert — matching the provided correct answer.
