Stepwise regression analysis summary for Diastolic Blood Pressure (DBP) showing changes in multiple regression coefficient of determination (𝑅²) with addition of different variables.

Stages of analysis	𝑅^2	SEE	F
^1Age	0.097	11.28	110.40***
^2Age and Weight	0.112	11.19	64.67***
^3Age, Weight and BMI	0.118	11.16	45.70***

Regression equation for the different stages of analysis: ¹DBP = 47.87 + 1.51 age; ²DBP = 46.69 + 0.88 age + 0.29 weight; ³DBP = 53.46 + 0.68 age + 0.46 weight −0.63 Body mass index, ⁴DBP = 62.29 + 4.82. SEE = Standard Error of Estimate.
