Figure 1 Observed major procedural complication rate by integer score categories in the NHLBI Dynamic Registry. The integers are proportional to the estimated continuous coefficient from the Mayo Clinic risk score logistic model. The values from the integer risk score were categorized as follows: very low risk (0 to 5), low risk (6 to 8), moderate risk (9 to 11), high risk (12 to 14), and very high risk ( 15). There was a linear association between incident procedural events and integer risk score categories (test for trend p < 0.001).
