Create an Evidence Brief

You are a senior MEAL specialist with expertise in evidence synthesis and knowledge management. Your task is to create a structured Evidence Brief that synthesizes findings across multiple sources on "topic" (from the material, if given).

Context:

• Topic: "topic" (from the material, if given)
• Scope: "scope" (from the material, if given)
• Number of sources to synthesize: "number" (from the material, if given)
• Sources (list titles or descriptions): "sources" (from the material, if given)
• Target audience: "audience" (from the material, if given)
• Intended use: "use" (from the material, if given)

Deliverables:

1. Brief Header

• Title (clear, specific, under 15 words)
• Subtitle with scope (geographic and temporal boundaries)
• Date of synthesis
• Author or commissioning organization
• Number of sources synthesized
• Classification: Evidence Brief (distinguish from policy brief, evaluation brief, or research summary)

2. Executive Summary (150-200 words)

• The question this brief answers
• The overall direction of evidence (what does the weight of evidence suggest?)
• The strength of the evidence base (strong, moderate, limited, or mixed)
• 2-3 headline conclusions
• The key implication for practice

3. Methodology Note (100 words)

• How sources were identified and selected
• Inclusion and exclusion criteria
• Limitations of this synthesis (not a systematic review, potential selection bias, geographic limitations)
• Quality assessment approach used

4. Source Quality Assessment Rate each source on methodological rigor:

Define quality rating criteria:

• High: Rigorous design (RCT, quasi-experimental with comparison), adequate sample, peer-reviewed or externally validated
• Medium: Mixed methods or pre-post design, reasonable sample, credible organization
• Low: Anecdotal, small sample, significant methodological concerns, or self-reported without triangulation

5. Synthesis of Findings Organize findings by thematic area. For each theme:

Theme title (e.g., "Impact on Food Consumption")

• Direction of evidence: What do most sources find? (Positive, negative, mixed, or insufficient)
• Strength of evidence: How confident can we be? (Strong, moderate, or limited, based on number and quality of sources)
• Convergent findings: Where do sources agree? Cite specific results.
• Divergent findings: Where do sources disagree? Explain why (context, methodology, population differences).
• Magnitude of effect: What is the range of reported effect sizes or outcomes?
• Conditions for success: Under what circumstances do positive results occur?
• Evidence gap: What remains unknown or under-researched?

Repeat for 3-5 thematic areas.

6. Evidence Map (Visual) Describe a 2x2 evidence map visualization:

• X-axis: Strength of evidence (limited to strong)
• Y-axis: Direction of evidence (negative to positive)
• Plot each thematic finding as a bubble (bubble size = number of supporting sources)

Provide the data needed for a designer or analyst to create this visual.

7. Implications for Practice

• 3-5 evidence-based recommendations, each linked to the synthesized findings
• For each: the recommendation, the supporting evidence (cite sources), the confidence level, and any caveats
• Distinguish between "the evidence strongly supports" and "the evidence suggests" and "insufficient evidence to determine"

8. Research and Evaluation Gaps

• List 3-5 specific questions that the current evidence base cannot answer
• For each gap, suggest the type of study needed (impact evaluation, process evaluation, cost-effectiveness analysis, longitudinal study)

9. References

• Full citation for each source in a consistent format
• Note whether each source is publicly available (with URL if possible)

Where the material is silent, write "Not in the material" rather than guessing.

Source material: Attached, or pasted below. Base everything above on it and do not invent details that are not in it.
