Conclusion
PPH
POSTPARTUM HEMORRHAGE
Our nomogram risk prediction method is both practical and straightforward to use, and it has the potential to be employed in clinical practice to predict the occurrence of PPH in twin pregnancies. Compared to other studies, our PPH prediction model involved a larger sample size and has a higher prediction accuracy. Furthermore, it is provided in the form of an easy-to-use online calculator, which can be saved to a computer or mobile phone and used to determine the estimated probability of postpartum hemorrhage by accessing the web-based application and entering data of the general state of pregnant women before birth directly. The current study has some limitations, such as data from a single site and only internal testing of the model; our model needs to be validated in more extensive and diverse populations.
