Main findings
In this study, we applied the FMF Stillbirth Risk Calculator based upon demographic characteristics in an independent case-matched dataset. We found that maternal, medical and obstetric history yield a high specificity and satisfactory sensitivity in discriminating between the outcomes live birth versus stillbirth. In acknowledgment of the challenge to predict adverse events in the presence of competing risks at later stages in pregnancy, the demographic maternal patterns, which may remain unaltered most often during pregnancy, may assist clinical risk assessment as early as at antenatal booking.
