Phenotypic, additive genetic correlations (rg), and non-shared environmental correlations (re) between PCL-C and TFEQ, along with 95% confidence intervals from AE models.
| Phenotypic Correlation with PCL-C total score (95% CI) | Proportion of Phenotypic Correlation |

|---|---|---|---|---|---|
| Measure | Genetic Effects | Environmental Effects | |||
| TFEQ Total | .32 (.25; .40) | 51% | 49% | .34 (.07; .58) | .29 (.11; .45) |

| Uncontrolled Eating | .31 (.23; .39) | 69% | 31% | .53 (.24; .84) | .16 (−.01; .33) |
| Emotional Eating | .29 (.22; .34) | 39% | 61% | .27 (−.05; .57) | .30 (.12; .45) |
Note: PCL-C = PTSD Checklist – Civilian Version; TFEQ = Three Factor Eating Questionnaire-Reduced 18; Cognitive Restraint = TFEQ-R18 Cognitive Restraint subscale; Uncontrolled Eating = TFEQ-R18 Uncontrolled Eating subscale; Emotional Eating = TFEQ-R18 Emotional Eating subscale; CI = Confidence Interval; rg = genetic correlation; re = non-shared environmental correlation*
