Table 1 Demographic characteristics of the investigated groups. SGA & AGA group: weight difference between twins from dichorionic pregnancy >15%, smaller twin with evidence of IUGR. AGAII group: weight difference between twins from dichorionic pregnancy <15%.

From: C-Peptide and leptin system in dichorionic, small and appropriate for gestational age twins—possible link to metabolic programming?
