LMWH: Low molecular weight heparin; UFH: Unfractionated heparin; HIT: Heparin induced thrombocytopenia; ICU: Intensive Care Unit. We compared the differences between the 2 groups (UFH and LMWH) in non-ICU patients using chi squared tests for categorical variables (sex, HIT testing results, Heparin Route) and using T-tests for continuous variables (age and platelets).
