BMI body mass index, SD standard deviation, COCs coexisting conditions, CNS indicates central nervous system disease and holds for patients with medically documented cerebral vascular accident, transient ischemic attack, or neurological deficit of central origin, PAD peripheral artery disease, OAC medication with oral anticoagulants and antiplatelet agents, ASA the American society of anesthesiologists physical status classification. Numbers in bracket indicate values presented in n (%) by group unless noted otherwise. *Percents may not total 100 due to missing data; P values represent the difference between the obese and normal weight group
