In this analysis, the following parameters remained significantly predictive for placental abruption: lower maternal age (OR 0.897, 95% CI: 0.807–0.997; p = 0.043); lower gestational age at delivery (OR 0.869, 95% CI: 0.814–0.926; p < 0.001); and higher CRP levels (OR 7.454, 95% CI: 1.538–36.121; p = 0.013). This evidence concerns the gene CRP and placental abruption.
