highly significantno p-value reported

However, analysis of the dependence of ORAC values of a range of antioxidants on their minimum bond dissociation energy (BDE) value (the lowest among the BDE values of C–H and O–H bonds in a molecule) showed that the regression coefficient was highly significant for both phenols di-substituted at the ortho position and phenols monosubstituted at the ortho position.
