Abstract

fetched live from OpenAlex

BACKGROUND: With new treatments for non-alcoholic fatty liver disease (NAFLD) on the horizon, it will be important to risk-stratify patients based on degree of fibrosis to allocate treatment to those at highest risk. No studies have examined the complication rates of liver biopsies in patients with NAFLD in the outpatient setting. METHODS: We conducted a retrospective chart review of all outpatient elective liver biopsies for NAFLD at a tertiary care centre over a 10-year period. Demographic variables and stage of fibrosis were recorded. Complications up to 1 week post-procedure were recorded. We used univariate logistic regression models to estimate the odds of major complications by fibrosis stage, age, sex, platelets, and international normalized ratio (INR). RESULTS: There were 582 biopsies reviewed in total. The mean age was 53 years. There was an even proportion of males to females. The mean fibrosis stage was 1.9; platelet count was 223.9, INR was 1, and partial thromboplastin time (PTT) was 31. Major complications occurred in 8 out of 582 biopsies (1.4%). Bleeding accounted for 6 of the major complications observed, while infection and pneumoperitoneum each occurred once. There were no statistically significant associations between age (odds ratio [OR] 0.97, 95% CI 0.92-1.03), female sex (OR 1.00, 95% CI 0.25-4.04), platelet count <150 (OR 0.59, 95% CI [-inf.], 3.86), INR >1.3 (OR 0.47, 95% CI 0.057-3.85), fibrosis stage, and complication rate. CONCLUSIONS: Our results are consistent with previous studies examining complication rates in other patient populations and clinical settings and support the overall safety of liver biopsies.

Teacher imitation

Not 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.
