The expression levels of SMAD4 in human follicular fluid GCs are associated with ovarian reserve and ART outcomes. A-C The expression levels of SMAD4 of GCs in the NOR and DOR groups (The original image of WB is shown in Figs. S7 and S8); D Negative correlation between the expression levels of miR-6881-3p and SMAD4 mRNA in GCs; E-K Correlations between the expression levels of SMAD4 mRNA in GCs and age, basic FSH, basic LH, basic estradiol, basic progesterone, AMH, and AFC; L-S Correlations between the expression levels of SMAD4 mRNA in GCs and LH on trigger day, estradiol on trigger day, progesterone on trigger day, number of retrieved oocytes, number of fertilized oocytes, number of normal fertilized oocytes, number of embryos, and number of good embryos. ** P < 0.01
