1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveThis study aimed to explore the dynamic role of bile acids (BAs) in metabolic improvements following bariatric surgery, specifically comparing the effects of silastic ring laparoscopic Roux-en-Y gastric bypass (SR-LRYGB) and laparoscopic sleeve gastrectomy (LSG) on BA composition and clinical parameters over a 5-year period.

methodsA cohort of patients with obesity and type 2 diabetes underwent SR-LRYGB or LSG. Principal component analysis was performed to evaluate BAs and clinical outcomes.

resultsDespite significant increases in the first year after surgery, BA levels returned to baseline after 5 years. However, principal component analysis revealed that certain BA profiles may contribute to long-term metabolic benefits.

conclusionsAlthough total BA levels return to baseline by 5 years after surgery, specific BA profiles, as identified by principal component analysis from oral glucose tolerance test data, are associated with sustained metabolic improvements. SR-LRYGB is associated with more durable metabolic benefits compared with LSG. However, given the use of the oral glucose tolerance test, which may not fully capture postprandial BA dynamics, further research using mixed-meal tolerance tests is needed to confirm these findings.
