MUC16 and hydrops fetalis: Higher sST2 was associated with the risk of death and the combined risk of death/HF readmission when CA125 was >35 U/mL [HR = 1.02 (CI 95%: 1.01–1.04), p = 0.006 and 1.02 (CI 95%: 1.01–1.03); p = 0.013 per increase in 10 ng/mL, respectively], but not when CA125 was ≤35 U/mL.
