[Retracted] The Low Endometrial Expression of Long Non-Coding RNA NORAD Is Associated with Recurrent Pregnancy Losses and Unexplained Infertility

Figure 1

Low endometrial expression of NORAD in RPL and UIF. (a) The relative expression level of NORAD in the endometrial tissues obtained from women with UIF (n = 32), women with RPL (n = 48), and fertile women (n = 62) was quantified by qRT-PCR. (b) Pearson correlation analysis of the serum level of E2 and the relative expression level of NORAD in the endometrial tissues of UIF. (c) Pearson correlation analysis of the serum level of E2 and the relative expression level of NORAD in the endometrial tissues of RPL.
