Regarding the prediction of SPTD at <34 weeks, the optimal cut-off values used for dichotomization are listed as follows: ≥2.23 ng/mL for AF M-CSF, ≥2.34 ng/mL for AF PTX3, ≥1.30 ug/mL for AF RAGE, ≥62.87 ng/mL for AF resistin, and ≥3.0 cm for cervical dilatation at presentation. The gene discussed is AGER; the disease is atrial fibrillation.
