SD	2.3	0.7
t-test (P value)	6.9 (0.001)a

^aP < 0.05.

LV: Left ventricular.

Table 3 Mean left ventricular mass and gender comparison between perinatal asphyxia with those without perinatal asphyxia

Comparison of LV mass by gender	Male	Female	t-test (P value) (95%CI)
With asphyxia	8.4 ± 2.4	7.5 ± 2.1	1.57 (0.120)
Without asphyxia	9.4 ± 1.4	9.9 ± 0.6	1.17 (0.520)

LV: Left ventricular.

Severity by Sanat
Mild	7.8 ± 2.3	F = 1.26, P = 0.289
Moderate	8.8 ± 2.5
Severe	7.1 ± 1.5

ANOVA: Analysis of Variance; LV: Left ventricular.
