Fig. 2From: Therapeutic Effects of Microsurgical Clipping at Different Time Points on Intracranial Aneurysm and Prognostic FactorsEvaluation of nomogram prediction model for poor prognosis. A ROC curve of internal validation for 102 IA patients undergoing microsurgical clipping from January 2017 to January 2019, which compares the established model and actual results. B ROC curve of external validation for 80 patients undergoing microsurgical clipping from February 2019 to August 2019, which assesses the accuracy of this modelBack to article page
