Establishment and multicenter external validation of a risk prediction model for de novo intracranial aneurysms based on a systematic review and meta-analysis of 19 cohorts

This prediction model is a convenient and intuitive tool for identifying high-risk patients with de novo IAs. Reasonable use of the model can not only aid in clinical decision-making but also play a positive role in the prevention of aneurysmal subarachnoid hemorrhage to a certain extent.
