Analyses of covariance with EEM parameters and FA value of STR.
| APS (SD) | HC (SD) | F | p | |
|---|---|---|---|---|
| EEM Parameters | ||||
| NEF | 28.3 (8.6) | 32.6 (7.7) | 4.419 | 0.041* |
| TESL (mm) | 1286.0 (670.9) | 1646.44 (725.6) | 4.967 | 0.031* |
| MESL (mm) | 43.6 (15.3) | 49.7 (14.7) | 4.378 | 0.042* |
| RSS | 6.0 (2.7) | 6.7 (2.6) | 0.200 | 0.657 |
| FA value | ||||
| STR_left | 0.395 (0.021) | 0.403 (0.020) | 5.713 | 0.021* |
| STR_right | 0.389 (0.018) | 0.394 (0.016) | 0.862 | 0.358 |
The FA values of the bilateral STR and EEM parameters are compared using an analysis of covariance that is adjusted for age and sex.
EEM, exploratory eye movement; NEF, number of eye fixations; TESL, total eye-scanning length; MESL, mean eye-scanning length; RSS, responsive search score; FA, fractional anisotropy; STR, superior thalamic radiation; SD, standard deviation; HC, healthy controls; APS, attenuated psychosis syndrome.
