*A total point score for a given patient is obtained by summing the patient’s age in years and the points for each predictor when present. The score corresponds with the following risk classes: 65 or less, class I; 66–85, class II; 86–105, class III; 106–125, class IV; and more than 125, class V. Patients in risk classes I and II are defined as being at low risk.
A total point score for a given patient is obtained by summing the points. The score corresponds with the following risk classes: 0, low risk; 1 or more, high risk. Empty cells indicate that the variable was not included.
The variables were combined into a single category of chronic cardiopulmonary disease.
