The effect of each of these variables on IUGR was significant [Log10 CDKN1C expression, Exp (B) 4.91, 95% CI 1.09–22.10, p = 0.038; preeclampsia, Exp (B) 5.78, 95% CI 1.12–29.73, p = 0.05], indicating an independent effect of each of these factors on IUGR. The gene discussed is CDKN1C; the disease is preeclampsia.
