^aModel 1 is a stepwise linear regression model. Significance level for entering the model was 0.05. F = 7.85, adjusted R² = 0.1063.

^bModel 2 is a linear regression model including all factors investigated in the study. F = 2.47, adjusted R² = 0.1357.

^cData are regression coefficient (95% confidence interval).
