Independent variables | B(SE) | OR (95% CI) | P-value |
|---|
Age at NCM | -0.23 (0.12) | 0.79 (0.63–1.00) | 0.050 |
Capillary loss (< 6/mm) | 1.38 (0.60) | 3.98 (1.22–12.99) | 0.022 |
- Variables associated with SRP in the univariate analysis (p < 0.10) were considered for inclusion in the multivariate logistic regression model. Variables included in the model were: age at NCM and capillary loss. The number of capillaries was not included because of its correspondence to capillary loss. Chi2 (df = 3) = 9.94. Nagelkerke pseudo R2 = 0.18. % PRP correctly predicted = 98.4. % SRP correctly predicted = 27.8. % overall correctly predicted = 82.9. ANA positivity was not included in this model. Negative B values are negatively correlated to SRP. The last column shows p-value (in bold: p < 0.05).
