Identifying predictors of early postoperative hypokalemia is crucial for managing patients effectively. This study aims to develop an interpretable predictive model to predict postoperative hypokalemia in patients with PA and recognizes individualized significant parameters contributing to the predictive outcomes, thereby facilitating early intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study investigated postoperative hypokalemia in 280 patients with PA. We developed a Transformer\u2010based predictive model, CliTab\u2010Transformer, and compared it with an XGBoost\u2010based model and a multilayer perceptron (MLP)\u2010based deep learning model. Model performance was evaluated using metrics such as accuracy, precision, recall, F1 score, and ROC\/PR curves, based on five\u2010fold cross\u2010validation. Model interpretability was assessed using a novel Transformer\u2010Explainability method to identify significant parameters contributing to individual predictions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>CliTab\u2010Transformer outperformed XGBoost and MLP in predicting postoperative hypokalemia, showing higher accuracy (0.836 vs. 0.775 vs. 0.771), F1 score (0.845 vs. 0.792 vs. 0.766), sensitivity (0.838 vs. 0.833 vs. 0.771), and AUC (0.835 vs. 0.807 vs. 0.676). The model's interpretability analysis revealed that the preoperative factors, including gender, hypertension, serum potassium concentration, and disease duration, are significantly predictive of postoperative hypokalemia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our model outperforms XGBoost in predicting early postoperative hypokalemia in patients with pituitary adenomas.
