Receiver operator characteristic curve analysis of AF concentrations of HMGB1 for the identification of patients without microbial-associated intra-amniotic inflammation who subsequently delivered within seven days after amniocentesis. AF HMGB1 concentration of 8.55 ng/mL had an area under the ROC curve of 0.67 (95% CI 0.55 – 0.78; p=0.005), a sensitivity of 46% (16/35), a specificity of 84% (71/85), a positive predictive value of 53% (16/30), and a negative predictive value of 80% (71/90) for the identification of patients who subsequently delivered within 7 days.
