Simple Slopes Analysis for the Maternal Perceived Stress × Prenatal PAH Exposure Interaction Effect on CA1, CA3, and CA4/Dentate Gyrus Subfield Volumes

Subfields PAH Exposure B SE t p 95% CI
CA1 Lower −0.13 0.18 −0.70 .487 −0.50 to 0.24
Higher −0.81 0.24 −3.34 .002 −1.30 to −0.32
CA3 Lower −0.12 0.17 −0.71 .484 −0.47 to 0.23
Higher −0.94 0.23 −4.12 <.001 −1.40 to −0.47
CA4/Dentate Gyrus Lower −0.10 0.19 −0.53 .598 −0.48 to 0.28
Higher −0.78 0.25 −3.13 .004 −1.29 to −0.27

Each simple slope was independently tested for significance using a t test (n = 37: nhigher = 19, nlower = 18).

PAH, polycyclic aromatic hydrocarbon.
