  1. P.POS/NEG/GEN/TOT – PANSS positive/negative/general/total subscales
  2. REAL.DIS. – Liddle's reality distortion factor
  3. DISORG. – Liddle's disorganisation factor
  4. PSY.POV. – Liddle's psychomotor poverty factor
  5. Bold font indicates the correlations explaining a priori hypothesis
  6. FCLEFT/Z/RIGHT – Fronto-central absolute power values of main frequencies
  7. (D)/(T)/(A)/(B) – delta (1.5–3 Hz), theta (3–7.5 Hz), alpha (7.5–12.5 Hz), beta (12.5–20 Hz)
  8. * – p < 0,05
  9. ** – p < 0,01
