First validation of the childhood lupus low disease activity state (cLLDAS) definition in a real-life longitudinal cSLE cohort

To validate the childhood lupus low disease activity state (cLLDAS) definition in cSLE by describing differences in time to reach first adult LLDAS (aLLDAS) versus cLLDAS. Secondly, to analyse positive and negative predictors for maintaining cLLDAS for at least 50% of follow-up time (cLLDAS-50) and for the occurrence of damage.
