The LEAP randomized trial, reported by Du Toit, et.al in the New England Journal of Medicine in February 2015 identified over 500 children in the UK ages 4 to 10 months who showed some sensitivity to peanut protein. They randomly assigned them to two groups: Peanut avoiders: parents were told to not give their kids any food which contained peanuts Peanut eaters: parents were given a snack containing peanut protein and told to feed it to their child several times per week (target dose was at least 6g of peanut protein per week). At age 5 years, children were tested with a standard skin prick to see if they had an allergic reaction to peanut protein(yes or no) What is the explanatory variable? Is it categorical or quantitative? whether or not a child developed a peanut allergy, categorical the amount of protein each child was given, quantitative the proportion of children who developed peanut allergy, categorical whether or not the child was exposed to peanut protein, categorical What is the response variable? Is it categorical or quantitative? the amount of protein each child was given, quantitative whether or not the child was exposed to peanut protein, categorical the proportion of children who developed peanut allergy, categorical whether or not a child developed a peanut allergy, categorical
