Ursodeoxycholic Acid Treatment–Induced GLOBE Score Changes Are Associated With Liver Transplantation-Free Survival in Patients With Primary Biliary Cholangitis
Bibliographic record
Abstract
INTRODUCTION: Treatment of primary biliary cholangitis (PBC) can improve the GLOBE score. We aimed to assess the association between changes in the GLOBE score (ΔGLOBE) and liver transplantation (LT)-free survival in patients with PBC who were treated with ursodeoxycholic acid (UDCA). METHODS: Among UDCA-treated patients within the Global PBC cohort, the association between ΔGLOBE (ΔGLOBE 0-1 : during the first year of UDCA, ΔGLOBE 1-2 : during the second year) and the risk of LT or death was assessed through Cox regression analyses. RESULTS: Overall, 3,775 UDCA-treated patients were included; 3,424 (90.7%) were female, the median age was 54.0 (interquartile range [IQR] 45.9-62.4) years, and the median baseline GLOBE score was 0.25 (IQR -0.47 to 0.96). During a median follow-up of 7.2 (IQR 3.7-11.5) years, 730 patients reached the combined end point of LT or death. The median ΔGLOBE 0-1 was -0.27 (IQR -0.56 to 0.02). Cox regression analyses, adjusted for pretreatment GLOBE score and ΔGLOBE 0-12 , showed that ΔGLOBE was associated with LT or death (adjusted hazard ratio 2.28, 95% confidence interval 1.81-2.87, P < 0.001). The interaction between baseline GLOBE score and ΔGLOBE 0-1 was not statistically significant ( P = 0.296). The ΔGLOBE 1-2 was associated with LT or death (adjusted hazard ratio 2.19, 95% confidence interval 1.67-2.86, P < 0.001), independently from the baseline GLOBE score and the change in GLOBE score during the first year of UDCA. DISCUSSION: UDCA-induced changes in the GLOBE score were significantly associated with LT-free survival in patients with PBC. While the relative risk reduction of LT or death was stable, the absolute risk reduction was heavily dependent on the baseline prognosis of the patient.

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.
