Horvath probe sets were reduced to match the probes available for PREG.

coef = coefficient, SE = standard error, PSS = perceived stress scale total score, GAAD = gestational age at delivery, BA = Horvath-derived biological age estimates.

Maternal chronological age was included as a covariate in all models.
