Abstract

fetched live from OpenAlex

BACKGROUND & AIMS: Diagnosis of preclinical compensated cirrhosis (occult cirrhosis, OC) is challenging due to lack of clinical findings. We evaluated prevalence and outcomes of OC by transient elastography (TE, Fibroscan(®)). METHODS: Eight hundred and seventy-one patients with compensated chronic liver disease (CLD) and TE examination were divided into: (i) OC (TE ≥ 13 kPa and no sign of cirrhosis, including absence of thrombocytopenia and signs of advanced liver disease on ultrasound or gastroscopy); (ii) clinically evident cirrhosis (TE ≥ 13 kPa with signs of cirrhosis); (iii) non-cirrhotic CLD (TE < 13 kPa). Outcomes included hepatocellular carcinoma (HCC), esophageal varices and ascites. Late diagnosis of outcomes was defined as HCC stage ≥intermediate by BCLC or variceal bleeding. RESULTS: Occult cirrhosis represented 12% of the cohort and 37% of cirrhotic patients. Independent predictors of OC were age [odds ratio (OR) 1.15; 95% confidence interval (CI), 1.04-1.26], HIV co-infection (OR 3.53; 95% CI, 1.85-6.76) and APRI (OR 2.63; 95 CI, 1.87-3.71). During a median follow-up of 24 (interquartile range 20-37) months, OC received less surveillance than clinically evident cirrhosis, with fewer ultrasounds (2.7 ± 1.5 vs 3.6 ± 2; P < 0.001) and gastroscopies (2 ± 0.8 vs 2.6 ± 1.4; P < 0.001). Incidence of outcomes was 3.5/100 per person-years (PY) (95% CI, 0.1-6.9) in OC, 0 in non-cirrhotic CLD and 9.8/100 PY (95% CI, 0.3-19.3) in clinically evident cirrhosis (P < 0.001). Late diagnosis occurred more in OC than clinically evident cirrhosis (60 vs 15%, P = 0.01). CONCLUSIONS: Occult cirrhosis is a frequent and under-monitored clinical entity associated with short-term risk of outcomes. TE may help early diagnosis, prompt initiation of surveillance and specific therapy for an otherwise unrecognized condition.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
