Similar patterns were present when correlations were determined separately for the two groups (autism: r = 0.22, p = 0.44 for AQ and T:E2; r = − 0.44, p = 0.10 for EQ and T:E2; r = 0.51, p = 0.05 for oxytocin and AQ; r = 0.11, p = 0.69 for oxytocin and EQ; neurotypical: r = 0.25, p = 0.24 for AQ and T:E2; r = − 0.14, p = 0.43 for EQ and T:E2; r = − 0.05., p = 0.80 for oxytocin and AQ; r = 0.18, p = 0.35 for oxytocin and EQ), although statistical significance was not achieved with the smaller sample sizes. Here, OXT is linked to autism.
