| Ostial lesion | 2.2 | 1.0 to 4.7 | 0.034 | 2 |
↵6-150 Risk points for a simplified risk function; the weights are assigned in proportion to the logarithm of the corresponding odds ratio from the multivariate analysis. The patients' total risk score is calculated as the sum of the risk points of all properties that apply.
CI, confidence interval.
