| Odor detection threshold scoresa | ||||
| Lyral detection threshold | −4.22 (0.77) | −4.18 (0.84) | −4.29 (0.68) | −4.49 (0.93) |
| Citralva detection threshold | −4.52 (0.93) | −4.26 (0.72) | −4.99 (1.15) | −4.96 (0.92) |
Note: FEP, First-Episode Psychosis; SAP, Schizophrenia and schizoaffective disorder; MAP, Mood associated psychosis; HC, Healthy controls.
aLower scores reflect better detection threshold performance.
