Peanut allergy in relation to heredity, maternal diet, and other atopic diseases: results of a questionnaire survey, skin prick testing, and food challenges

Two authors' errors occurred in this paper by J O'B Hourihane and others (31 August, pp 518–21).

Firstly, the third and fourth sentences in the second paragraph of the results should have read: “Mc Nemar's χ2 analysis of parental concordance showed that asthma was equally common in mothers and fathers (χ2 = 0.17, P = 0.67, 95% confidence interval 0.07 to 1.53, odds ratio 1.0). Hay fever was also equally common (0.54, P = 0.46, 0.86 to 1.41, 1.1). Eczema was more common (5.73, P = 0.01, 1.07 to 2.1, 1.5) and any food allergy twice as common (13.14, P = 0.0003, 1.31 to 2.57, 1.82) in mothers.”

Secondly, the third sentence of the second paragraph of the discussion should have read “twice as likely” rather than “more than four times as likely.”
