Anemia in patients ten years after bariatric surgery.
Article in International journal of obesity (2005), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundMore than 10% of the global population has a BMI above 35. Bariatric surgery is an efficient way to treat this condition. Unfortunately, there is a risk of nutritional deficiencies. The number of studies after a longer time span is scarce. The aim of this study was to determine the occurrence of anaemia five and ten years after bariatric surgery and how it was related to substitution therapy. PATIENTS AND
methodsRegistry data from individuals having primary bariatric surgery in the Scandinavian Obesity Surgery Registry (SOReg) from 2007 to 2022 and with a follow-up at five or ten years was retrieved. Demographic data including weight, as well as method of surgery, Hb levels, supplementation, PPI use and stomal ulcerations were recorded.
resultsIn total, 39,992 individuals (mean age 41 years, range 18-74, 77% women) could be included. The majority, 78%, had undergone laparoscopic Roux-en-Y gastric bypass. After five years, 2838/13,944 women (20.3%) and 456/4049 men (11.2%) had anaemia. After ten years, 644/3400 women (18.9%) and 178/947 men (18.8%) had anaemia. The use of oral iron increased from 40 to 45%, and the need for parenteral iron intake increased from 5 to 11%.
conclusionsAnaemia is a significant but manageable condition five and ten years after bariatric surgery. Despite the prescription of oral iron supplements to 45% ten years after surgery, the Hb levels could still not be fully restored. Consequently, the importance of follow-up visits and continuous supplementation is emphasised.
