Lupus & antiphospholipid syndrome
Predictors of British Isles Lupus Assessment Group-based outcomes in patients with systemic lupus erythematosus: Analysis from the Systemic Lupus International Collaborating Clinics Inception Cohort
Authors' conclusion
Baseline predictors of response in SLE can help identify patients in clinic who are less likely to respond to standard therapy.
Study context
- Population
- Patients with SLE in the SLICC international inception cohort
- Participants
- 1,492 vs 924
- Exposure
- Inception enrolment vs Active disease
- Inception enrolmentn = 1,492
- Active diseasen = 924
- Outcome
- Predictors of BILAG-based outcomes: MCR (reduction to classic BILAG C in all domains, steroid dose ≤7.5 mg and SLEDAI ≤ 4) and Improvement (≤1B score in previously active organs; no new BILAG A/B; stable or reduced steroid dose; no increase in SLEDAI)
- Follow-up
- 12 months
Methodological detailsprediction model development, international, univariate and multivariate logistic regression with Least Absolute Shrinkage and Selection Operator (LASSO), cross-validation in randomly split samples
- Prediction model development
- International
- Univariate and multivariate logistic regression with LASSO
- Cross-validation in randomly split samples
