From: Relationship between duration of illness and cardiac autonomic nervous activity in anorexia nervosa
| Anorectic patients ( n = 14) | Controls ( n = 22) | p value | |
|---|---|---|---|
| mean ± SD | mean ± SD | ||
| Heart rate | 56.1 ± 12.5 | 70.0 ± 15.1 | 0.007 |
| Normalized low-frequency power (nu) | 38.8 ± 17.2 | 34.7 ± 12.5 | 0.422 |
| Normalized high-frequency power (nu) | 42.3 ± 16.3 | 38.8 ± 20.1 | 0.395 |
| Low-/high-frequency power ratio | 1.2 ± 1.1 | 1.3 ± 1.1 | 0.788 |
