Significant differences when evaluating only patients with a genetic test. Trisomy 13, 18, and 21 were evaluated in 530 patients and more than half of the patients received at least karyotyping or SNP-array. An abnormal genetic test is seen more often in complex-CDH (P < 0.001) and defect size C differs from the missing data category (P < 0.001) as substantially more abnormal genetic tests are described in the later. Within a column each characteristic measure that does not share a subscript letter (a−b) differs significantly from those with different subscript letters (a−b) whose column proportions do not differ significantly from each other at the 0.05 level. WES, whole exome sequencing; MD, Missing data; CDH-C, CDH patients with associated defects; CDH-I, CDH patients without other associated defects; CDH-MD, CDH patients in which no additional information was registered; POE, Paraoesophageal hernia; EV, Eventration; BL, Bilateral hernia; AGT, abnormal genetic test; NPC, no pathogenic changes.
