Patients who underwent cardiac surgery and were aged 65 or older were included. The relationship between preoperative GNRI and POD was investigated using logistic regression. We determined the added predictive value of preoperative GNRI for POD by measuring the changes in the area under the receiver operating characteristic curve (AUC) and calculating the net reclassification improvement (NRI) and integrated discrimination improvement (IDI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 4286 patients were included in the study, and 659 (16.1%) developed POD. Patients with POD had significantly lower GNRI scores than patients without POD (median 111.1 vs. 113.4,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Malnourished patients (GNRI\u2009\u2264\u200998) had a significantly higher risk of POD (odds ratio, 1.83, 90% CI, 1.42\u20132.34,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) than those without malnutrition (GNRI\u2009&gt;\u200998).
