Roux-en-Y Gastric Bypass as a Treatment for Hepatic Iron Overload: An Exploratory Study.
Article in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
backgroundExcess bodily iron content is commonly associated with obesity and metabolic associated medical conditions and is thought to lead to cardiovascular disease. The effect of Roux-en-Y gastric bypass (RYGB) on hepatic iron overload remains to be determined.
objectiveTo assess the evolution of histologically proven hepatic iron overload after RYGB.
methodsThis is an exploratory historical cohort study in which 42 individuals who underwent RYGB, and then a second surgical procedure had paired liver biopsies collected. Hepatic iron overload and NAFLD features were assessed through histopathological examination. Biochemical iron metabolism parameters were also assessed.
resultsThe mean age at RYGB was 47 ± 10.2 years and 92.9% were female. The average time elapsed between RYGB and the second surgical procedure was 20.6 ± 15.4 months. The mean percentage of total weight loss between the two procedures was 26.7 ± 9.4%. Significant reductions in ferritin (220.8 ± 202.9 vs. 101.6 ± 116.7 ng/mL; p = 0.006), hemoglobin (13.7 ± 1.8 vs. 12.1 ± 2.6 g/dL; p = 0.01), and red blood cell count (4.7 ± 0.7 vs. 4.3 ± 0.5 10
conclusionRYGB led to a significant decrease in hepatic iron overload, emerging as a possible therapeutical tool for this condition in individuals with obesity and dysmetabolic iron overload syndrome.
