Comparison of carotid measures between PHPT and NOMAS control subjects, adjusted for gender, diabetes, systolic and diastolic blood pressure, triglycerides, and BMI

	PHPT	Controls	Normal range
IMT (mm)a	0.96 ± 0.39b	0.91 ± 0.09	0.7–0.9
Strain (%)	9.1 ± 21.5	8.5 ± 5.0	6–12
Stiffnessa	6.2 ± 24.2b	8.3 ± 5.8	<6
Distensibilitya	0.19 ± 0.54	0.17 ± 0.13	>0.425
MCPT (mm)a	2.09 ± 1.00	2.08 ± 0.76	<1.9

Results are mean ± sd. Normal ranges are from Cardiovascular Health Study and NOMAS (11). 

^aIndices that were abnormal in both cases and controls. 

^bPHPT vs. control group: ^bP < 0.0001; ^cP < 0.05.
