ASA, American Society of Anesthesiologists; BMI, body mass index, CI, confidence interval; COPD, chronic obstructive pulmonary disease; DVT/PE, deep vein thrombosis/pulmonary embolism; ECOG, Eastern Cooperative Oncology Group; OR, odds ratio; PVD, peripheral vascular disease; SD, standard deviation; WHO, World Health Organization; IQR, interquartile range.
Odds ratio for age per 10-y increment and per doubling for CA-125.
Cardiac event represents patients with a history of coronary artery disease, myocardial infarction or other cardiac event.
Cardiovascular risk factors represent patients with a history of hypertension, hyperlipidemia or peripheral vascular disease.
Other pulmonary disease represents patients with asthma, sleep apnea, or other pulmonary diagnoses.
Thrombocytosis defined as preoperative platelet count >450 × 109/L.
