  1. The resulting standardized regression coefficient (β) with a 95% confidence interval (95% CI) for a factor (independent variable) indicates the increase or decrease in standard deviations (SDs) of a dependent variable (IMT), when that particular factor increases with 1 SD and all other variables in the model remain unchanged
