These patients were divided into a good prognosis group (n = 207) and a poor prognosis group (n = 96) . An improved machine learning model was employed to analyze patient clinical data, aiding in the construction of a prediction model for poor prognosis in intracranial aneurysm endovascular intervention. This model simultaneously performed feature selection and weight determination. Logistic multivariate analysis was used to validate the selected features. Additionally, a visualization system was developed to automatically calculate the risk level of poor prognosis.  \nResults: In the training set, the improved machine learning model achieved a maximum F1 score of 0 .8633 and an area under the curve (AUC) of 0 .9118. In the test set, the maximum F1 score was 0.7500, and the AUC was 0.8684. The model identified 10 key variables: age, hypertension, preoperative aneurysm rupture, Hunt-Hess grading, Fisher score, ASA grading, number of aneurysms, intraoperative use of etomidate, intubation upon leaving the operating room, and surgical time. These variables were consistent with the results of logistic multivariate analysis.  \nConclusions: The application of improved machine learning models for the analysis of patient clinical data can e􀀀ectively predict the risk of poor prognosis following endovascular intervention for intracranial aneurysms at an early sta","cbCaiu8fQlyhyydG","https://ap.wps.com/l/cbCaiu8fQlyhyydG","pdf",1684205,1,9,"English","en",105,"# Introduction\n# Methods\n# Results\n# Conclusions","[{\"question\":\"What is the main purpose of the study?\",\"answer\":\"To evaluate whether an improved machine learning model can predict poor prognosis after endovascular intervention for intracranial aneurysms and to develop a visualization system for risk calculation.\"},{\"question\":\"How were patients selected and grouped?\",\"answer\":\"A total of 303 patients treated with endovascular intervention at four hospitals between January 2022 and September 2023 were included, and they were divided into a good prognosis group (n=207) and a poor prognosis group (n=96).\"},{\"question\":\"Which variables were identified as key predictors?\",\"answer\":\"The model identified 10 key variables: age, hypertension, preoperative aneurysm rupture, Hunt-Hess grading, Fisher score, ASA grading, number of aneurysms, intraoperative use of etomidate, intubation upon leaving the operating room, and surgical time.\"}]","Construction of a poor prognosis prediction and visualization system for intracranial aneurysm endovascular intervention treatment based on an improved machine learning model -
