Table 2 Lateral ventricle volume of 165 normal infants with different age (mm3)

From: Measurement of lateral ventricle volume of normal infant based on magnetic resonance imaging

Group (month age) Mean month age Gender Number of infants Total lateral ventricle volumes (mm3)
1~3 (n = 12) 2.5 Male 7 10,359.00
Female 5 8994.60
4~6 (n = 33) 5.2 ± 0.8 Male 22 12,174.41 ± 6160.34
Female 11 9273.54 ± 3462.47
7~9 (n = 51) 8.1 ± 0.8 Male 32 13,308.13 ± 4815.42
Female 19 12,625.47 ± 5382.09
10~12 (n = 69) 11.5 ± 0.8 Male 41 13,885.41 ± 7027.05
Female 28 11,141.93 ± 4328.60
One-way analysis of variance Male: F = 0.915, p > 0.05; female F = 1.641, p > 0.05
Male: F = 0.552, p > 0.05; female F = 1.899, p > 0.05
  1. Using one-way analysis of variance, the difference of lateral ventricle volume between male and female infant was of no statistical significance (male: F = 0.915, p > 0.05; female: F = 1.641, p > 0.05), considering that the number of infants with age lower than 3 months was only 12, which was too less. Removing such group, the differences among the other three groups were still of no statistical significance (male: F = .552, p > 0.05; female: F = 1.899, p > 0.05)
