Evaluation of Progression From Preclinical to Systemic Autoimmune Rheumatic Disease: Novel Use of the <scp>European Alliance of Associations for Rheumatology</scp>/American College of Rheumatology Systemic Lupus Erythematosus Classification Criteria as an Outcome Measure
Bibliographic record
Abstract
OBJECTIVE: Our objective was to evaluate the development of a systemic autoimmune rheumatic disease (SARD) in undifferentiated and asymptomatic individuals with antinuclear antibodies (ANAs). We comparatively evaluated those who did and did not develop a SARD and fulfillment of classification criteria. METHODS: We conducted a cohort study of undifferentiated and asymptomatic patients with ANAs who were assessed for the development of a SARD. The primary outcome was a diagnosis of a SARD over a two-year period. We assessed fulfillment of classification criteria. Risk ratios (RRs) were used to evaluate differences among those who did and did not progress to a SARD. RESULTS: We evaluated 207 asymptomatic ANA-positive or undifferentiated patients, of whom 23 (11%) progressed to a SARD, whereas 187 (89%) did not progress. Progressors developed systemic lupus erythematosus (SLE) (n = 11 [48%]), Sjögren disease (n = 5 [22%]), systemic sclerosis (n = 3 [13%]), rheumatoid arthritis (n = 1 [4%]), and from ANA-positive to undifferentiated connective tissue disease (n = 3 [13%]). Fever (RR 0.89, 95% confidence interval [CI] 0.8-0.93) and antiphospholipid antibodies (RR 0.89, 95% CI 0.87-0.93) occurred less frequently, whereas arthritis (RR 1.74, 95% CI 1.20-2.55) occurred more frequently in progressors. Progressors to SLE had arthritis (91%), whereas none developed delirium, psychosis, or nephritis. Among patients with SLE, 100% fulfilled the EULAR/American College of Rheumatology (ACR) SLE criteria (sensitivity 91.7%, specificity 100%), whereas 73% fulfilled the 1997 ACR SLE criteria (sensitivity 81.8%, specificity 98.9%). CONCLUSION: Most undifferentiated/asymptomatic individuals with ANA do not progress to a SARD over a two-year period. SLE progressors appear to have mild disease in the short term. The EULAR/ACR SLE criteria have improved ability to identify those who develop SLE.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
