BMI: body mass index, CAD: coronary artery disease, CHF: congestive heart failure, COPD: chronic obstructive airway disease, CVC: central venous catheter, DM: diabetes mellitus, ESRD: end-stage renal disease, PEEP: positive end expiratory pressure, PICC: peripherally inserted central catheter, and VTE: venous thromboembolism. * value was calculated with Fischer’s exact test.
