Table 1. Participants’ characteristics.
In the groups involved in real time RT-PCR study (A), gestational age differed whatever the classification criteria used (P≤.05) but stayed within the normal range for term deliveries. This difference was therefore ignored. Women who delivered LBW babies were of lower gravidity (P =.026) and were younger (P =.025) than those who delivered normal birth weight babies. Groups of participants involved in the immunohistochemistry (IHC) analysis (B) were comparable for all criteria (except birth weight for the group with LBW: P =.019). Values are medians with (in brackets) 25th and 75th centiles. Mann-Whitney’s test.
