Univariate regression analysis and ROC study results of novel echocardiographic parameters in subpopulation of patients with HF.

LVEF/LAVI ≤ 0.6	0.56	2.1 [1.1–4.1]	0.023
HF with mid-range EF
LVEF/LAA ≤ 1.5	0.68	2.2 [1.1–4.6]	0.033
LVEF/LAVI ≤ 0.9	0.60	3.8 [3.6–9.2]	0.002
HF with preserved EF
LVEF/LAA ≤ 1.8	0.70	4.1 [1.9–9]	0.001
LVEF/LAVI ≤ 1.1	0.71	4.4 [1.7–11.6]	0.003
HF with mid-range EF and HF with reduced EF
LVEF/LAA ≤ 2	0.67	4.3 [2.1–8.9]	0.001
LVEF/LAVI ≤ 1	0.72	4.5 [2.3–8.5]	0.001

^ap-values refer for the differences between LAAT (+) and LAAT (-) groups.

AUC, an area under the curve; EF, ejection fraction; HF, heart failure; LAA, left atrial area; LAVI, left atrial volume index; LVEF, left ventricular ejection fraction; OR, odds ratio.
