Contribution of PTX3 and C-reactive protein level or the combination of the two to the risk prediction of prevalent cardiovascular disease.

*The multivariable logistic regression model was adjusted c. The composite cardiovascular endpoint subsumes all cases of ischemic stroke, TIA, myocardial infarction, peripheral artery disease, definite angina and previous revascularization procedures (n = 95).
†Variable chi-square is the 1-degree-of-freedom likelihood ratio chi-square statistic with P values for inclusion of each variable separately to the multivariable base model, with larger values indicating greater improvement in fit. The+sign indicates the addition of either PTX3 level, or C-reactive protein level, or both to the base model considering standard risk factors.
‡The calibration P values was calculated with the Hosmer-Lemeshow calibration statistics comparing observed and predicted risk in decile categories of predicted risk. Higher values for the calibration P value reflect better fit.
§The C statistic represents the area under the receiver-operating-characteristic curve. Higher values for the C statistic reflect better fit.
#non normally distributed PTX3 and hsCRP levels were log-transformed.
