SLE patients in the development cohort were randomly divided into the training cohort and the internal validation cohort at a 7:3 ratio. Laboratory variables were collected and compared by univariate logistic regression modeling. Multivariate logistic regression was further used to develop predictive models and plot a risk nomogram for OS. Receiver operating characteristic (ROC) and calibration curve analysis were used to assess model validity and accuracy. Decision curve analysis was used to assess net clinical benefit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Indexes including anti\u2010SSA antibody, anti\u2010SSB antibody, proteinuria, occult blood in urine, age, eosinophil ratio, hematocrit, platelet, direct bilirubin, indirect bilirubin, rheumatoid factor, immunoglobulin A, prothrombin time, and ferritin were included in the predictive model. The nomogram showed a wide range of predictive ability. The area under the curve (AUC) of the ROC curve for the training cohort was 0.874 (0.851\u20130.896), the AUC for the internal validation cohort was 0.877 (0.843\u20130.911), and the AUC for the
