Based on a population of jewish children in england vs. a population of jewish children in Israel, literally a repeat population from the first study 8 years ago. The paper in question also states: "Moreover, it should be noted that since the change in Australian guidelines in 2016, consumption of peanut during the first year of life increased from 28.4% before the guidelines (2007-11) to 88.6% after the implementation of the guidelines (2016-18). Despite this change, a recent publication has shown no decline in the observed prevalence of peanut allergy in Australia in 2020, which remained stable at 3.1%." It's been tried in a large population with literally zero effect.
