NA indicates not applicable.

A Dupriez score of 0 was assigned for a hemoglobin level greater than 100 g/L and a white blood cell count between 4 × 10⁹/L and 30 × 10⁹/L, a score of 1 for either a hemoglobin level less than 100 g/L or a white blood cell count greater than 30 × 10⁹/L or less than 4 × 10⁹/L, and a score of 2 if both the hemoglobin level and white blood cell count were in the aberrant ranges.
