  • *Not all patients had weight and serum creatinine documented in the chart.

  • †Combined popliteal, femoral, common femoral and iliac.

  • ‡Combined PE with PE+DVT and report it all as PE.

  • §PESI score could not be calculated in nine patients due to missing variable(s).

  • CrCl, creatinine clearance; DVT, deep vein thrombosis; PE, pulmonary embolism; PESI, Pulmonary Embolism Severity Index; VTE, venous thromboembolism.
