Multivariate Logistic Regression Analysis of Electrocardiogram Findings Using Age, Sex, and GAA Repeat Length

	LVH	RVH	LAD	RAD	ST-T Δ	Normal ECG
Age	P = .026^*	P = .001^*	P = .217	P = .013^*	P = .837	P = .295
Sex	P = .006^*	P < .001^*	P = .042^*	P = .482	P = .401	P = .004^*
GAA	P = .668	P = .042^*	P = .523	P = .093	P = .039	P = .003^*
Overall P Value	P = .002^*	P < .001^*	P = .008^*	P < .001^*	P = .062	P < .001^*

Denotes significance
