5 | CONCLUSION
We developed the first nomogram and
online tool that accurately predicts the risk of SPTB at <32
weeks in twin pregnancy, whose screening performance has been found to
be superior to either risk factor alone. It can provide application
value to complement the existing clinical evidence, which assists the
counselling and decision-making of clinical treatment for twin pregnancy
with differing risks of PTB.
