However, the only allopregnanolone association that survived robust regression was the one with SERT binding in the prefrontal cortex (slope = -0.011, SD = 0.003, β = -0.196, p < 0.001), whereas the robust regressions between allopregnanolone and SERT binding in the pallidostriatum and hippocampus were in borderline significance (pallidostriatum; slope = -0.162, SD = 0.083, β = -0.236, p = 0.054, hippocampus; slope = -0.049, SD = 0.027, β = -0.187, p = 0.071).
