*Not all patients had weight and serum creatinine documented in the chart.
†PE and PE+DVT are reported together.
‡PESI score could not be calculated in nine patients due to missing variable(s).
§Combined popliteal, femoral, common femoral and iliac.
CrCl, creatinine clearance; DVT, deep vein thrombosis; ED, emergency department; PE, pulmonary embolism; PESI, Pulmonary Embolism Severity Index; VTE, venous thromboembolism.
