Estimated trend and level changes between pre- and post-intervention in terms of mean number of new takeaways opening within management zones around schools per quarter per LA within the sample, and differences at 12, 24 and 48 months, and at the maximum time interval (72 months for all management zones, 66 months for full management zones, 72 months for town centre exempt zones and 69 months for time management zones).
