	Female			Male
	Dysautonomia (N=87)	No dysautonomia (N=47)	P-value	Dysautonomia (N=4)	No dysautonomia (N=5)	P-value
LV EDV/BSA (ml/m ² )	57.8 ± 17.2	65.0 ± 15.1	0.03	59.9 ± 10.4	73.3 ± 19.8	0.3
LVIDd (mm)	44.3 ± 6.0	46.7 ± 5.3	0.3	44.0 ± 2.6	48.2 ± 6.7	0.4
LV mass/BSA (g/m ² )	65.8 ± 16.8	72.0 ± 18.5	0.2	74.4 ± 22.8	73.0 ± 13.6	0.9

Echocardiographic data expressed as mean ± s.d.

BSA: body surface area

LVEDV: left ventricular end systolic volume

LVIDd: left ventricular internal diastolic diameter

^†

Echocardiographic data available for individuals with and without dysautonomia respectively for the following parameters: LVIDd, N=69 and N=36; LVEDV/BSA, N=60 and N=45; LV mass/BSA, N=67 and N=40.
