Eating related to reward sensitivity summed z score 1.34 (1.68) −1.78 (1.74) <0.001 ***
Non-food reward sensitivity summed z score −0.79 (2.1) 0.9 (1.9) 0.03*
Sensitivity to punishment summed z score 0.51 (1.66) −0.87 (2.89) 0.022*

Independent Student t test, Mann-Whitney U test, or Pearson χ2 tests were used as appropriate. Means (SD) or frequencies are reported.

Abbreviation: AUC, area under the curve.
