PTX3 and atrial fibrillation: Similarly, in the multivariate analysis, with respect to the prediction of SPTD at <28 weeks, high AF levels of PTX3 (≥2.34 ng/mL) and resistin (≥62.87 ng/mL) but not those of M-CSF (≥2.23 ng/mL) were still significantly independently associated with SPTD at <28 weeks when adjusting for advanced cervical dilatation (≥3.0 cm) (Table 3).
