Values are means ± SE or count (%) as appropriate. BMI = body mass index; PICC = peripherally inserted central catheter; TPN = total parenteral nutrition; AKI = acute kidney injury; CKD = chronic kidney injury; HTN = hypertension; PVD = peripheral vascular disease; CAD = coronary artery disease. *Benjamini-Hochberg method of p-value adjustment was used to control the false discovery rate at 5%.
