| Typical AN | Atypical AN | |||||
|---|---|---|---|---|---|---|
| Measures | n | Mean (SD) | n | Mean (SD) | F | Partial η2 |
| Duration of disorder (yr) | 62 | 8.5 (7.9) | 36 | 10.0 (6.6) | 0.95 | NS |
| Lowest BMI (kg/m2) | 67 | 14.0 (1.7) | 43 | 16.5 (2.6)*** | 38.1 | .262 |
| Highest BMI (kg/m2) | 62 | 22.9 (6.5) | 39 | 25.7 (4.6)* | 5.63 | .054 |

| Ideal BMI (kg/m2) | 66 | 17.3 (1.9) | 44 | 19.3 (2.2)*** | 23.2 | .177 |
Note. Partial η2 < .01 small, <.06 medium and < .14 large [57]
