How EvidAsk Works
The Answer Process
Behind the Scenes: When you ask a question, EvidAsk searches across millions of indexed papers, analyzes relevant content, synthesizes the evidence, and generates a response with proper citations.
Step-by-Step:
- Query Understanding: AI interprets your question intent
- Literature Search: Relevant papers identified
- Evidence Extraction: Key findings pulled from papers
- Synthesis: Information combined into coherent answer
- Citation Generation: Sources linked for verification
Response Components
Each EvidAsk response includes:
| Component | Description |
|---|---|
| Direct Answer | Clear response to your question |
| Supporting Evidence | Key findings from literature |
| Citations | Linked references to source papers |
| Confidence Level | How certain the AI is |
| Related Questions | Suggestions for exploration |
Using EvidAsk
Asking Questions
Best Practices for Questions:
| Do This | Not This |
|---|---|
| Be specific: "What is the effect of exercise on HbA1c in type 2 diabetes?" | Too broad: "Tell me about diabetes" |
| Use proper terms: "randomized controlled trials" | Vague: "good studies" |
| One topic per question | Multiple unrelated questions |
| Include context when relevant | Assume AI knows your background |
Example Conversations
Clinical Question:
You: What is the NNT for statins to prevent one cardiovascular event?
EvidAsk: Based on meta-analyses of statin therapy for primary prevention:
• The number needed to treat (NNT) ranges from 50-100 over 5 years
to prevent one major cardiovascular event in low-risk patients.
• For high-risk patients (established CVD), the NNT is much lower,
approximately 10-20 over 5 years.
• The CTT Collaboration meta-analysis (Lancet 2010) found that for
every 1 mmol/L reduction in LDL cholesterol, there was a 22%
relative reduction in major cardiovascular events.

Methodology Question:
You: When should I use GRADE vs ROBINS-I?
EvidAsk: These tools serve different purposes in systematic reviews:
**ROBINS-I (Risk of Bias in Non-randomized Studies of Interventions)**
• Use for: Assessing individual study quality
• Applies to: Non-randomized studies (cohorts, case-control)
• Domains: Confounding, selection, classification, deviations,
missing data, measurement, reporting
**GRADE (Grading of Recommendations Assessment, Development, Evaluation)**
• Use for: Rating certainty of evidence across studies
• Applies to: Bodies of evidence for specific outcomes
• Considers: Study design, RoB, inconsistency, indirectness,
imprecision, publication bias
**In Practice:**
Use ROBINS-I during data extraction to assess each study's RoB,
then use GRADE during synthesis to rate overall evidence certainty.

Follow-Up Questions
Continue conversations for deeper understanding:
- "Can you elaborate on the high-risk findings?"
- "What were the limitations of these studies?"
- "Are there any contradicting studies?"
- "Can you provide more recent evidence?"

Quality & Limitations
What EvidAsk Excels At
✅ Evidence-based medical/scientific questions ✅ Methodology and statistics guidance ✅ Quick fact-finding with citations ✅ Explaining concepts and relationships ✅ Comparing treatments or approaches
Limitations to Understand
| Limitation | Recommendation |
|---|---|
| Not a doctor | Don't use for personal medical advice |
| Knowledge cutoff | Verify for very recent developments |
| Citation accuracy | Always verify critical citations |
| Complex synthesis | Use for guidance, not final analysis |
Important: EvidAsk is a research support tool, not a replacement for expert judgment. Always verify important findings and consult appropriate professionals for clinical decisions.
