Effectiveness of Bariatric Surgeries for Metabolic Dysfunction-Associated Steatotic Liver Disease: A Systematic Review and Meta-Analysis
Bibliographic record
Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common liver disease worldwide and simultaneously the most common indication for liver transplants in Western countries This study aims to evaluate the effectiveness of laparoscopic sleeve gastrectomy (LSG) or Roux-en-Y gastric bypass (RYGB) on MDASLD histologically and biochemically. 14 studies met our criteria with a total population of 1942 who underwent LSG or RYGB 1–14. The Newcastle-Ottawa Scale (NOS) was used for quality evaluation of the included studies. Results: Both surgeries were effective in decreasing laboratory biomarkers like ALP, GGT, AST, and ALT with non-significant superiority of LSG over RYGB which did not significantly improve the AST level after one year. LSG showed more decrease in ALT levels (MD = −17.56, 95% CI = (−23.04, −12.089), p 0.001) and LSG was associated with increased change in NAS score with slight superiority. Both LSG and RYBG improve NAD and NASH outcomes after one and 10 years of surgery. However, randomized clinical trials with large samples are needed to confirm these results.

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.
