The interaction between maternal anxiety and tree cover on newborns’ PC 1 BDNF DNAm was suggestive but did not reach statistical significance ( β = −0.22 [95% CI: .−0.45, −0.01], p = 0.059) and the overall model was also not significant ( p = 0.10).

When using larger buffers (500 and 1000 m), the interaction effects approached significance but did not reach statistical thresholds ( p = 0.060 and p = 0.090, respectively), and the full models were not significant.
