Combination analysis of polymorphisms of miRNA machinery genes in RPL patients and control subjects according to the number of previous pregnancy losses.

Note: For AOR, OR was adjusted by age of participants. RPL = recurrent pregnancy loss; PL = number of pregnancy losses; AOR = adjusted odds ratio; CI = confidence interval; HWE = Hardy–Weinberg equilibrium.aFisher's exact test;bFDR-adjusted P value.
