Serum microRNA levels - comparison between non pregnant women and pregnant women in their third trimester.

For each microRNA, “delta CT” indicates the difference in median CT between the serum of pregnant women in the third trimester (n = 10) and non-pregnant women (n = 10). For each sample, the relative amount of the microRNAs was normalized by subtracting the average CT of the non-placenta-specific microRNAs. The fold change is the ratio of the median abundance in linear space, equal to the exponent (base 2) of the delta CT. P-values are calculated by a two-sided unpaired t-test.
