Table 4 Heart function assessment from the physicians

Categories	Incorrect answer
LVEF (n = 291)^a	58 (19.9%)
< 30% (n = 23) ^b	8 (34.8%)
30–54% (n = 73)	18 (24.7%)
≥ 55% (n = 195)	32 (16.4%)
RV enlargement and paradoxical septal motion (n = 291)	9 (3.1%)
Yes (n = 21)	4 (19.0%)
No (n = 270)	5 (1.9%)

^aThe proportion of wrong answers on LVEF was higher than on RV dysfunction, p < 0.001
^b The proportion of incorrect answers in patients with LVEF< 30% was the highest,
while the proportion of incorrect answers in patients with LVEF≥55% was the lowest, p < 0.001
LVEF left ventricular ejection fraction, RV right ventricle
