This inconsistency may be largely attributed to methodological limitations, particularly in variable selection and missing data handling. Consequently, the prognostic value of several key clinical predictors remains to be fully elucidated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This retrospective study included 390 patients with AIS who underwent EVT at Ningbo No.2 Hospital. All of them achieved successful reperfusion with modified Thrombolysis in Cerebral Infarction (mTICI) score \u2265 2b. Futile reperfusion was defined as a modified Rankin Scale score of 3\u20136 at 90-day. Missing data were handled with multiple imputation. Logistic regression models were built using a two step predictor selection process: first univariable screening with\n                      <jats:italic>p\u202f&amp;lt;<\/jats:italic>\n                      0.2; then further selection based on event count constraints. Only variables that were selected in all five imputed datasets, meaning a 100% selection frequency, were retained. Model performance measures were pooled following Rubin\u2019s rules.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Based on preoperative assessments integrating clinical, imaging, and laboratory markers, the final model comprised nine variables: National Institutes of Health Stroke Scale (NIHSS) score, Computed Tomography angiography-source images Alberta Stroke Program Early Computed Tomography Score (CTA-SI ASPECTS), time from onset to reperfusion (OTR), collateral circulation scores (CCS), C-reactive protein (CRP), glucose, white blood cell (WBC) count, neutrophil count, and monocyte count. The final model demonstrated good discriminative ability, with a pooled test AUC of 0.795 and a Brier score of 0.178. At the optimal threshold (mean 0.457), the model achieved a specificity of 0.822 and accuracy of 0.761, with positive net benefit across clinically relevant threshold probabilities on decision curve analysis. A nomogram incorporating the nine consistently selected predictors was developed to facilitate individualized risk prediction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We developed a multidimensional model integrating clinical, imaging, and laboratory markers to predict futile reperfusion following EVT in patients with anterior circulation stroke.
