Each value shows the estimated coefficient and the standard error for each coefficient is shown in brackets. **p < 0.01, ***p < 0.001. No standardized beta coefficients (β) represent the amount of change in a dependent variable due to a 1-unit change in the independent variable. R2 is a statistical measure of how well the regression predictions approximate the real data points. An R2 of 100% indicates that the regression predictions perfectly fit the data.
