Assessment of RNA regulatory molecular features detected in plasma and placental transcriptomes. A, B The density of expression abundance in preterm birth of different RNA biotypes compared in A plasma, and B placenta. C Numbers of differently expressed RNAs for different RNA biotypes. D Several placental cell type specific genes were differentially expressed in PTB in the maternal plasma cfRNA profile. E Several placental cell type specific genes were differentially expressed in PTB in the placental RNA profile. F The fold change of placenta-associated genes between PTB and FTB pregnancies. G The fold change of PTB-associated genes between PTB and FTB pregnancies. The orange indicates that the value of |log2 fold change| is higher in plasma, compared to the placenta group. *p-value < 0.05
