  • Critically analyze study designs using structured AI prompts that identify common methodological weaknesses
  • Generate evidence summary tables and clinical bottom lines from complex literature

Evidence Synthesis and Study Design Analysis

From Data to Meaning

You have extracted data from individual studies. Now the challenge is synthesis: What does the totality of evidence tell us? How certain can we be? Where are the gaps? AI excels at organizing and structuring this synthesis — while you provide the critical judgment.

The Evidence Synthesis Prompt

PROMPT TEMPLATE: Multi-Study Evidence Synthesis

I have extracted data from [n] studies addressing the question:
"[PICO question]"

STUDY SUMMARIES:
Study 1: [Author, Year] - [Design] - N=[n] - [Key finding
  with effect size and CI]
Study 2: [Author, Year] - [Design] - N=[n] - [Key finding
  with effect size and CI]
Study 3: [Author, Year] - [Design] - N=[n] - [Key finding
  with effect size and CI]
[continue for all studies]

Please synthesize:
1. OVERALL DIRECTION: Do the studies consistently support
   a benefit, harm, or no effect?

2. MAGNITUDE: What is the range of effect sizes observed?
   Is there clinical significance beyond statistical significance?

3. CONSISTENCY: How consistent are results across studies?
   If inconsistent, what factors might explain heterogeneity?
   (populations, doses, durations, outcome definitions)

4. STUDY QUALITY PATTERN: Do higher-quality studies show
   different results than lower-quality studies?
