  1. Results were obtained with a multivariate linear regression model. Variables included in the model were: age at NCM, and ANA and anti-ENA screening. ANA*anti-ENA was included as an interaction variable (not shown in table). All variables were included using the Enter method. Chi2 (df = 3) = 18.59. Nagelkerke pseudo R2 = 0.40. % PRP correctly predicted = 94.4. % SRP correctly predicted = 55.6% overall correctly predicted = 81.5. Negative B values are negatively correlated to SRP. The last column shows the p-value (in bold: p < 0.05)
