CONCLUSION
Our pilot study demonstrated that CGA absence was predictive of PTB and may be a useful adjunct to CL screening for improving PTB prediction. As the etiology of spontaneous PTB and cervical insufficiency is ill-defined and likely multifactorial, multimodal screening tools may be necessary for optimal prediction 44. We hope this inspires future research exploring CGA screening, such as via three-dimensional renderings or elastography, in populations with different risk profiles, in the context of various progesterone regimens, and in combination with cervical biomarkers or clinical phenotyping.
