Backward stepwise logistic regression multivariate analysis of factors associated with ability to complete the meal

Model 1				Model 2				Final Model
Factor	OR	95% CI	P- Value	Factor	OR	95% CI	P- value	Factor	OR	95% CI	P- value
BMI*	0.97	0.77 – 1.2	0.81	Age	1.15	0.89 – 1.49	0.29	BSA	19.7	5.1 – 75.7	<0.001
Age	1.13	0.83 – 1.5	0.44	BSA	4.97	0.3 – 82.0	0.26
BSA#	7.88	0.08 – 815.3	0.38

^*BMI = Body Mass Index

^#BSA = Body Surface Area

Each step of the analysis is shown with the final model only including BSA after both BMI and age have been removed.
