Table 3. Distribution of the number of vermian lobules in the DWM (n = 7) and control groups (n = 8).

	1–3 lobules	4–5 lobules	6–7 lobules	LS mean ± SE
Control (n = 8)	0 (0%)	3 (37.5%)	5 (62.5%)	6.15 ± 0.40	p < 0.001*
DWM (n = 7)	6 (85.7%)	1 (14.3%)	0 (0%)	2.30 ± 0.42

The number of vermian lobules in each fetus was calculated as the mean value of the 3 raters, and was divided into 3 categories: 1–3 lobules, 4–5 lobules, and 6–7 lobules. The values indicate the number of fetuses in each category. The numbers in parentheses represent the proportion of fetuses in each category within the DWM or control groups. The mean number of vermian lobules adjusted for gestational age differed significantly between the DWM and control groups.

LS mean, least-squares mean; SE, standard error.
