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

Stages of analysis	𝑅^2	SEE	F
^1Weight	0.248	10.80	337.80***
^2Weight and BMI	0.264	10.79	174.20***
^3Weight, BMI and AC	0.284	10.76	118.60***

Regression equation for the different stages of analysis: ¹SBP=76.53+0.84 weight; ²SBP = 82.53 + 0.97 weight −0.62 Body mass index; ³SBP=70.00+0.80 weight – 0.58 Body mass index + 0.27 Abdominal circumference; ⁴SBP=98.1+4.6. SEE = Standard error of estimate.
