IGHE and food allergy: In a sensitivity analysis that examined IgE‐mediated food allergy as measured by oral food challenge or based upon a panel assessment of clinical history and/or allergic sensitization by 1 to 2 years, total N = 1115 (1), was RR = 1.46, 95% CI 0.91 to 2.34. For parent report of a doctor diagnosis of food allergy at 1 to 2 years, total N = 1614 (3), and the pooled treatment effect was RR 1.02, 95% CI 0.80 to 1.31. No low risk of bias sensitivity analysis was possible
