R2 = Percentage of variance explained by the model; Adj R2 = Adjusted percentage of variance explained by the model; β = Standardized regression coefficient; CI = Confidence interval; p = p-value; VIF = Variance inflation factor. Note: VIF > 5 suggests collinearity issue. * = p < 0.05; ** = p < 0.01.
