The integrated model that included both PEA and OEA had substantially enhanced effects compared with model 3 (when each lipid was the sole predictor), with PEA having a larger standardized effect size (β = −0.281, p = .008) ( Figure S3 ) than OEA; OEA had an effect size approaching significance (β = 0.209, p = .059) but in a direction opposite to that of PEA.
