This premise seems rather insane for multiple reasons:
1. London remained significantly more polluted throughout the entirety of the study. The effects of the NPI had only marginal impact on pollution levels yet the spread of NO2 levels between London and Luton started out and remained enormous... London retained basically double the pollution level of Luton throughout the entirety of the study period. In relative terms the shrinking delta between them was tiny. London started out at ~35 NO2 and Luton ~15... London ended up at about ~28 NO2 vs ~13 for Luton.
I suppose there could be some kind of very specific magical threshold of NO2 pollution in children by which such effects could just happen to materialize yet absent extraordinary evidence this isn't a reasonable conclusion. The more reasonable conclusion is NO2 at the levels measured don't have any statistically relevant effect on expiratory volume within the constraints of the study.
They in my view are being intentionally dishonest throughout by the continuous use of relative change between London and Luton instead of simply referencing absolute numbers. They are leading the reader to make assumptions that are inherently nonsensical BS.
2. There is at no point in absolute terms any year measured with a difference in expiratory volume that exceeds the CI between London and Luton. There is no statistically significant difference yet the paper and the TFA keep pretending otherwise by invoking the same relative vs absolute trick as for the NO2 levels.
3. Comparing people living in huge cities with 20x the population of a much smaller city is BS to begin with. You compare like to like especially given well known lifestyle differences that directly impact health.
