Figure 1. Plasma OXT and AVP levels and linear regression analysis.

Figure 1

Median value for each group is shown by a horizontal bar. Mothers of autistic children displayed a significantly lower plasma level of OXT when compared to mothers of normal children (A). Plasma AVP levels were also significantly reduced in mothers of autistic children compared to mothers of normal children (B). A positive correlation was shown between log-transformed plasma OXT levels and log-transformed plasma AVP levels (r = 0.727, p<0.001) (C). AM: mothers of autistic children; NM: mothers of normal children; OXT: oxytocin; AVP: Arg-vasopressin.
