GSTM1 and Anxiety: Oxy-Hb in rFPC correlated negatively with anxiety severity (Ch30: <i>r</i> = -0.15, <i>p</i> < 0.001; Ch33: <i>r</i> = -0.16, <i>p</i> < 0.001), with similar patterns across additional channels.<h4>Conclusions</h4>rFPC hypoactivation differentiates clinically significant anxiety from lower-symptom groups and scales with symptom severity during EAMT.
