Significance, p-value, of the between-group ANCOVA analyses of the effect of body mass index (BMI) or waist circumference (WC) on lateral ventricle (LV) volume/intracranial volume (ICV), T1 , T2 , or mean diffusivity (MD).
| Obese vs. Lean | Overweight vs. Lean | Obese vs. Overweight | |||||
|---|---|---|---|---|---|---|---|
| BMI | WC | BMI | WC | BMI | WC | ||
| CP volume/ICV | 0.18 | 0.33 | 0.26 | 0.12 | 0.91 | 0.51 | |
| LV volume/ICV | 0.03 | 8.90 x10-3 | 0.76 | 0.34 | 0.45 | 0.39 | |
| T1 | 0.12 | 0.04 | 0.37 | 0.48 | 0.03 | 0.54 | |
| T2 | 0.49 | 0.38 | 0.11 | 0.63 | 0.11 | 0.71 | |
| MD | 0.39 | 0.07 | 0.12 | 0.73 | 0.03 | 0.75 | |
All between-group comparisons were controlled for age, age2, sex, and ethnicity. For CP volume/ICV, between-group comparisons were controlled for age, age2, sex, ethnicity, and LV volume. Bold indicates significance (p < 0.05) or close to significance (p < 0.1).
