- Relationship between selected risk factors and pSS–ILD
- Descriptive analyses showed differences in risk of pSS–ILD for seventeen indices mentioned above. We conducted Spearman correlation analyses for continuous variables and selected one member of each pair of correlated variables (r > 0.3 and p < 0.05) to include into the logistic regression model to avoid multicollinearity. With those steps, disease duration and KL-6 were selected to include in the final model.
