Basic statistics: means and SDs of each single variable, Males (M) and females (F) in the two classes, intra-uterine growth retardation (IUGR) and appropriate for gestational age (AGA).

IUGR: intra-uterine growth retardation; AGA: appropriate for gestational age; Gest Age: gestational age; PRO: total protein content per mg of placental tissue; mRNA_BP1: IGF Binding Protein-1 relative gene expression; mRNA_BP2: IGF Binding Protein-2 relative gene expression; mRNA_IL6: Interleukin-6 relative gene expression; mRNA_IGF1: Insulin-like growth factor-1 relative gene expression; mRNA_IGF2: Insulin-like growth factor-2 relative gene expression; PLA_IGF2: Insulin-like growth factor-2 normalized placental lysate concentration; PLATNF: Tumor Necrosis Factor-α normalized placental lysate concentration; PLAIL6: Interleukin-6 normalized placental lysate concentration; PLA_BP2: IGF Binding Protein-2 normalized placental lysate concentration; males (M) and females (F).
