The nutritional status of the participants was evaluated assessed on the day of admission, the day before discharge, and on the 1st, 3rd, and 6th month postoperatively. Data were analyzed using the latent class growth model, generalized linear model and logistic regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 474 eligible elderly patients completed all follow-ups. Three distinct nutritional status trajectories were identified: \u201cSevere Malnutrition-Rapid Improvement Group,\u201d \u201cModerate Malnutrition-Rapid Improvement Group,\u201d and \u201cPersistent Low Malnutrition Risk Group.\u201d The \u201cSevere Malnutrition-Rapid Improvement Group\u201d and \u201cModerate Malnutrition-Rapid Improvement Group\u201d had persistent severe and moderate malnutrition, respectively, from the day before discharge to 1\u202fmonth postoperatively, and both constituted populations in urgent need of clinical intervention; additionally, their quality of life across multiple domains was significantly lower than that of the \u201cPersistent Low Malnutrition Risk Group\u201d at 6\u202fmonths postoperatively (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
