Figure 1

Figures A and B illustrate the trajectory of maternal cortisol across gestation that is associated with the infant cortisol response to the heel-stick. Data were analyzed continuously using growth curve modeling. For illustrative purposes, prenatal maternal cortisol trajectories (with standard error bars) are displayed for mothers of infants with the highest cortisol response (top quartile) and the lowest cortisol response (bottom quartile) at 20 minutes (Figure 1A) and 40 minutes (Figure 1B) after the heel-stick.
