Interaction effect among age and SARS-CoV2 infection on SAA levels.

Outcome	Age	SARS-CoV2 Infection	Mean (95% CI)	p-Value	p-Value for Interaction
SAA (ng/mL)	mean − SD: 46 years	Negative	47.1 (34.3; 64.7)	0.1780	0.0087
	mean − SD: 46 years	Positive	58.3 (42.4; 80.4)	0.1780
	mean: 59 years	Negative	34.4 (26.2; 45.0)	<0.0001
	mean: 59 years	Positive	59.3 (44.8; 78.5)	<0.0001
	mean + SD: 72 years	Negative	25.1 (17.7; 35.5)	<0.0001
	mean + SD: 72 years	Positive	60.3 (44.3; 82.3)	<0.0001

Association between SAA and case control group was evaluated at three selected levels of age (mean-standard deviation (SD), mean, and mean + SD value). Data are expressed as adjusted geometric means and 95% confidence interval. Data are adjusted for gender, BMI, smoking, and antihypertensive medications. SAA, Serum amyloid A.
