  1. Notes: Backward multiple linear regression analysis. Multicollinearity and interaction term were checked and not found (tolerance < 1.00 and VIF < 10). Linear relationship between the independent and outcome variable was checked using scatter plot of residuals. Normality of response variable was checked using histogram and box-plot of residuals. Model assumptions are fulfilled
