The nomogram was developed based on the variables screened using the least absolute shrinkage and selection operator regression and multivariate logistic regression. The predictive efficiency of the nomogram was validated using both internal and external validation cohorts. Furthermore, the association between AKI and 90-day functional outcomes and mortality was analyzed based on propensity-score matching.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Five risk factors for AKI were identified and used to construct a nomogram: baseline National Institutes of Health Stroke Scale score, preoperative creatinine level, pneumonia, acute heart failure, and hypotension. The nomogram exhibited good predictive performance as assessed by the area under the curve, calibration plots, and decision-curve analysis. In the propensity-score matched cohorts, AKI remained significantly associated with 90-day worse neurological outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We developed and validated an online dynamic nomogram with high predictive accuracy for predicting the risk of AKI in patients with AIS undergoing EVT, which is beneficial for clinical decision-making.
