Bland‒Altman analysis of repeated measurements of energy loss and pressure difference in the D3 phase of the left ventricle and right ventricle in the same foetus

	LV D3 EL-AVE	LV D3 IVPD	RV D3 EL-AVE	RV D3 IVPD
sample	14	14	14	14
mean difference	-4.43	0.07	11.52	0.08
95% CI	-35.47-26.61	-0.07-0.21	-23.01-46.06	-0.03-0.19
P (H0: Mean = 0)	0.76	0.28	0.48	0.12

95% CI: 95% confidence interval of the difference between the two groups; LV D3 EL-AVE: left ventricular late diastolic average energy loss; LV D3 IVPD left ventricular late diastolic pressure difference; RV D3 EL-AVE: left ventricular late diastolic average energy depletion; RV D3 IVPD: left ventricular late diastolic pressure gradient
