Introduction:
The relationship between preoperative VE/VCO
Evidence Acquisition:
PubMed and Embase were queried until November 2023 to identify studies exploring the link between preoperative VE/VCO
Evidence Syntthesis:
Fourteen observational studies, involving 7637 patients, were included. Higher preoperative VE/VCO
Conclusions:
Elevated preoperative VE/V CO
