Data is given ± SD for scalar variables. LVEDD, Left ventricular end diastolic volume; LVESD, Left ventricular end systolic volume; LVEF, Left ventricular ejection fraction; E/A, ratio of mitral early flow to atrial flow; E/Em, ratio of mitral early flow to early diastolic movement of mitral annulus; NC/HT, hypertrabeculation/noncompaction. Provided p value refers to significance level for comparisons between all groups.
*
Significantly higher compared to lowest values.
**
Significantly higher compared to all groups.
