    The study analyzed 1,529 adults who underwent gastrectomy for gastric cancer, focusing on the impact of perioperative nutritional support.

  • 2

    Postoperative albumin improvement occurred in 15.2% of patients, with higher rates in the nutritional support group compared to the no/standard support group.

  • 3

    Nutritional support was associated with a higher change in albumin levels, but the association with binary albumin improvement was less precise.

  • 4

    A gradient boosting model was developed to predict albumin improvement, achieving an AUROC of 0.711 and an AUPRC of 0.422.

  • 5

    The findings suggest that perioperative nutritional support may mitigate early postoperative declines in serum albumin after gastrectomy.
