Candidate predictors were extracted from electronic health records (EHRs) and anesthesia records. Stepwise logistic regression based on the Akaike information criterion (AIC) was applied for feature selection. A multivariable logistic regression model was developed and evaluated using an internal train\u2010test split of the same single\u2010center dataset. A nomogram was constructed to visualize the prediction model. Model performance was assessed using the area under the curve (AUC), calibration curve, Hosmer\u2013Lemeshow test, and decision curve analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 1092 patients were included in this study, of which 433 cases (39.7%) were diagnosed with IOH. After feature selection using stepwise logistic regression, the model retained six key predictors: age, fasting duration, basal temperature, emergency surgery, estimated duration of surgery, and anesthesia induction time. The multivariable logistic regression model achieved an AUC of 0.7731 in the training set and 0.7475 in the test set. The Hosmer\u2013Lemeshow test indicated good calibration (\n                      <jats:italic>\u03c7<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u20093.8795, df\u2009=\u20098,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.8678).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The logistic regression model performed well in predicting the risk of IOH in patients undergoing gynecological laparoscopic surgery.
