Prediction of scleroderma renal crisis in patients of SSc: insight from the Chinese Rheumatism Data Center (CRDC) cohort study

Rheumatology (Oxford)Published Retrospective multicentre observational study

Authors' conclusion

A Nomogram with improved predictive performance compared with the previous one was developed in a larger sample size in China.

Study context

Population
SSc patients registered in the Chinese Rheumatism Data Center (CRDC) database
Exposure
New multi-predictor Nomogram vs an existing model for predicting scleroderma renal crisis (SRC)
Outcome
Prediction of SRC risk by a new multi-predictor Nomogram
Methodological detailsprediction model development and validation, matched 1:4 controls, LASSO regression, bootstrap resampling for internal and external validation
  • Prediction model development and validation
  • Matched 1:4 controls
  • LASSO regression
  • Bootstrap resampling for internal and external validation

Main finding

As reported in the abstract

Nomogram performance for predicting SRC
  • Predictors: myocardial involvement, SSc subtype, anaemia, platelet count and disease duration
  • AUC showed strong discrimination in both training and validation datasets
  • Calibration curves and Hosmer-Lemeshow test indicated good agreement between predicted and actual outcomes
  • Decision curve analysis (DCA) demonstrated greater clinical net benefit
  • Net reclassification improvement (NRI) and integrated discrimination improvement (IDI) showed significant improvement over the previous model

Observational data: associations, not effects.
