Mean P300 amplitudes (µV) of healthy controls and patients with OSAS at Fz, Cz and Pz electrode sites
| Electrode | Healthy controls (n = 34) | OSAS patients (n = 54) | p | Difference % |
|---|---|---|---|---|
| Fz | 3.89 ± 1.63 | 2.03 ± 1.68 | < .001 | 48 |
| Cz | 4.03 ± 1.50 | 1.97 ± 1.85 | < .001 | 51 |
| Pz | 3.69 ± 1.48 | 2.09 ± 1.73 | < .001 | 43 |
Data are presented as mean ± standard deviation (SD)
OSAS obstructive sleep apnea syndrome, µV microvolt. Difference % is calculated with “(Healthy controls-OSAS patients)/Healthy controls × 100” formula
