Multivariate logistic regression predicting composite healthcare-associated infections

	OR*	95% CI*	P values*
Composite healthcare-associated infection current procedural terminology linear risk	0.33	0.30 to 0.36	<0.0001
Age	0.98	0.97 to 0.99	0.0001
American Society of Anaesthesiologists class	1.05	1.02 to 1.08	<0.0001
Underweight short	0.89	0.60 to 1.33	0.56
Overweight short	1.43	1.05 to 1.92	0.02
Underweight tall	0.75	0.37 to 1.52	0.42
Overweight tall	1.15	0.90 to 1.45	0.27

Both composite healthcare-associated infection current procedural terminology linear risk and age were continuous variables.
