Interaction Analysis P-values

Cardiac mechanics parameter	Interaction term	P-value for the interaction term
Global longitudinal strain, %	Waist:hip ratio × sex	0.44
	Waist:hip ratio × race*	0.96
	Waist:hip ratio × obesity	0.89
e’ velocity, cm/s	Waist:hip ratio × sex	0.002
	Waisthip ratio × race*	0.053
	Waisthip ratio × obesity	0.43

^*The 8 participants who self-identified as “other race” were excluded from these analyses.

In addition to the specified interaction term, the models above were adjusted for age, sex, race, physical activity (average number of blocks walked per day), body-mass index, systolic blood pressure, heart rate, smoking status, serum fasting glucose, total cholesterol, estimated glomerular filtration rate, anti-hypertensive medication use, left ventricular mass, wall motion abnormalities, ejection fraction, center, speckle-tracking analyst, and image quality.
