Impact of Prehabilitation Components on Oxygen Uptake of People Undergoing Major Abdominal and Cardiothoracic Surgery: A Network Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Background/Objectives: Patient preoperative cardiorespiratory physical fitness measured by maximal oxygen consumption (VO2max) is highly relevant to postoperative outcomes, with low VO2max associated with a greater symptom burden and a greater prevalence of long-term treatment-related cardiovascular disease risk factors in patients undergoing surgery. A network meta-analysis (NMA) was conducted to determine the effects of different components of prehabilitation, including exercise, nutrition, psychological intervention, and different combinations of the aforementioned interventions, on oxygen consumption in people undergoing major abdominal or cardiothoracic surgery. Methods: A literature search was conducted from inception to December 2025. Randomized controlled trials on th
