Overview
Togias A et al.. J Allergy Clin Immunol 2017 · PMID 28065278 · DOI 10.1016/j.jaci.2016.10.010
Infants, especially those at high risk, should be given peanut-containing foods early (from 4-6 months) to prevent peanut allergy.
Does the study support the specific claim? No · Methodological quality: high
Plain-language summary
Study explained simply
- What did the researchers want to find out?
Prevent peanut allergy.
- How was the study done?
Expert guideline.
- How many people, animals or samples were studied?
Not applicable.
- What was actually found?
Early introduction by risk level.
- How large was the observed effect?
79% relative reduction (LEAP post hoc).
- What do the results mean in everyday life?
Avoiding peanuts in babies can backfire; introduce them under guidance.
- What are the study's limitations?
Some recommendations rely on extrapolation.
- What does it say about Elawady's specific claim?
Limits any avoidance advice derived from C-LEG-11.

5. Actual results
- Results
Guideline 1: infants with severe eczema, egg allergy or both should have age-appropriate peanut-containing food introduced as early as 4-6 months (testing strongly considered). Guideline 2: mild to moderate eczema - around 6 months, at home. Guideline 3: no eczema or food allergy - peanut-containing foods freely introduced with other solids. LEAP-based post-hoc analysis: 79% relative risk reduction in low-sensitisation infants.
- Absolute risks
See LEAP (I-LEG-11): absolute difference 11.8 points in SPT-negative infants (stats/C-LEG-11_leap_arr.py).
- Authors' conclusion
Early introduction of peanut-containing foods is recommended according to risk level.
6. Strengths

- Full text read (PMC)
7. Weaknesses
- Guideline 2 based on extrapolation (low quality of evidence)
8. Risk of bias
- Orienting tool
- none applicable

- Full formal assessment
- no
- Overall risk of bias
- low
- Rationale
Formal guideline process.
9. Assessment of the statistical interpretation
Not applicable.
10. Relevance to the specific claim
Shows that the correct conclusion from peanut-anaphylaxis data is targeted avoidance in allergic people and early introduction in infants, not general avoidance (C-LEG-11 safety note).
11. Independent contrary findings
None.
12. Transferability to Germany and Europe
Consistent with European practice.
13. Overall methodological judgement
Key guideline for the safety note.
