total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 2 points
• maximum score: 38 (32 given in text, but this may be been highest observed)
• A score of 2 to 14 is associated with a very low mortality but afterwards it rises rapidly.
• A score of 20 has a mortality of around 12%. A score of 25 has a 50% mortality. A score of 30 has a mortality of about 80%.
Performance:
• The area under the ROC curve is 0.83.
