Further comprehensive meta-analysis concerning the IFN-α and IFN-β exposure demonstrated that the risks of live birth (OR 0.89, 95% CI: 0.62–1.27), spontaneous abortion (OR 1.09, 95% CI: 0.73–1.63), stillbirth (OR 1.38, 95% CI: 0.51–3.72), preterm delivery (OR 1.24, 95% CI: 0.85–1.81), and maternal complications (OR 0.72, 95% CI: 0.38–1.38) were not increased in patients exposed to IFNs. Here, IFNA1 is linked to Stillbirth.
