Nonadjusted model adjusts for the following: no covariates were adjusted for. Minimally adjusted model: we only adjusted for sex, ethnicity, and age. Fully adjusted model: we adjusted for age, sex, ethnicity, heart rate, BUN, anion gap, hematocrit, NOAC, and ANTIPLT; PEG/PEJ. BUN: blood urea nitrogen; NOAC: new oral anticoagulant; ANTIPLT: antiplatelet drugs; PEG/PEJ: percutaneous endoscopic gastrostomy/jejunostomy; Ref: reference.
