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

Obesity remains a major barrier to kidney transplantation and is associated with inferior transplant outcomes. We conducted a PRISMA 2020-compliant systematic review and meta-analysis comparing sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) in kidney transplant candidates and recipients. PubMed/MEDLINE, Embase, Scopus, and Cochrane CENTRAL were searched through January 2026. Eleven observational studies involving 2,553 patients (1,461 SG; 1,092 RYGB) were included. SG was associated with lower mortality (RR 0.46, 95% CI 0.32-0.66) and graft loss (RR 0.39, 95% CI 0.21-0.73) than RYGB, while access to transplantation was similar between procedures. SG also demonstrated fewer nutritional complications and greater pharmacokinetic stability. Current evidence suggests that SG may be the preferred bariatric procedure among kidney transplant recipients, although prospective comparative studies are needed.
