Poisson GAMMs–adjusted temporal trends of predicted PaO₂/FiO₂ ratio, Hb, Ppeak, Na+, and K+ stratified by CVP levels. Notes: The fitted plot illustrated the temporal trends of the predicted CVP over the five measurement time points (T0–T4), stratified by three key CVP levels [low (25th percentile), median, and high (75th percentile)]. The predictions were adjusted for age, weight, height, actual tidal volume, and intraoperative use of furosemide. The solid lines and shaded areas represented the predicted means and their respective 95% confidence intervals,respectively. Hb, hemoglobin; Ppeak, peak airway pressure; Na⁺, arterial sodium concentration; K⁺, arterial potassium concentration. Measurement time points were defined as baseline at the start of surgery (T0), and after intraoperative irrigation volumes of 5000 mL (T1), 10,000 mL (T2), 15,000 mL (T3), and 20,000 mL (T4).
