Data are presented as mean and standard deviation (SD), standard error of the mean (SEM), frequencies or percentage (%). *p-value as determined with the t-test, Mann-Whitney U, X2 or Fisher’s exact test. cCMV, congenital cytomegalovirus; Preg, pregnancies; MRI, magnetic resonance imaging; EFW, estimated fetal weight. **Controls: healthy fetuses. AC, abdominal circumference. MCDA twin pregnancy in cCMV cases.
†Seventeen cCMV cases with a live newborn included. The bold values indicate significant differences.
