Fig. 1From: Growth patterns and associated risk factors of congenital malformations in twinsMalformation metrics to intertwin birthweight difference mean ratio: Malformation class distribution are reported as box plots and are distributed equally lower than zero in all malformed twins, except for those with cardiovascular malformations (p = .0000083). Solid circles in the box plot graphs represent outliers with values that lies more than one and a half times the length of the box.
