  1. The weight of the samples are given in the last column. Comparisons performed by t-test showed no statistical difference in sample weights between the groups: non-pregnant CMP-dist vs. early pregnant CMP-dist (P = 0.4), non-pregnant CMP-dist vs. term pregnant CMP-dist (P = 0.4), early pregnant CMP-dist vs. term pregnant CMP-dist (P = 0.8), term labor whole CMP vs. preterm labor whole CMP (P = 0.2).
