PLOD1 and obesity disorder: Using backwards elimination, we identified LH–dlHPC rsFC (β = −9.886, P = 0.044) and LH–left dlHPC CI (β = −14.676, P = 0.037) as the only independent predictors of obesity, with a variance inflation factor (VIF) of 1.32 (VIF < 2.5 suggests negligible collinearity between variables).
