Evaluation of nutritional, anthropometric, and psychological outcomes in different metabolic and bariatric surgery techniques: a follow up study.
Article in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundMetabolic and bariatric surgery (MBS) is a suitable solution for the treatment of morbid obesity. Investigating an MBS method that has the best outcomes has always been the main concern of physicians. The current study aimed to compare nutritional, anthropometric, and psychological complications of individuals undergoing various MBS Techniques.
methodsA total of 96 subjects, who had been already referred to the obesity clinic of Firoozgar Hospital, Tehran, Iran, for MBS, were selected for the study and were followed for one year after MBS. The dietary intakes of the participants were assessed using a Food Frequency Questionnaire (FFQ) on a daily, weekly, monthly, or yearly basis. The mental health of participants was done via the Symptom Checklist 90 Revised. Furthermore, the In-Body 720 bioelectrical impedance device was used to obtain the body composition of the participants at the beginning and the end of the study.
resultsThe mean age of the participants was 39.5 ± 9.5 years. All anthropometric indices including weight, Body Mass Index (BMI), protein content, fat mass, and fat mass percentage decreased after Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), and sleeve gastrectomy (SG) surgeries (P < 0.05). After adjustments for confounders, no significant difference was observed in the magnitude of the changes in body composition between the three Techniques (p > 0.05). Energy and carbohydrate intake significantly decreased after surgeries in all three groups (p < 0.05), but comparing the methods no significant difference was revealed (p > 0.05). Furthermore, the results indicated that there was a significant relationship between the mental health of patients before and after surgeries (p < 0.05).
conclusionOverall, all three methods of surgery contributed to the improvement of the nutritional, anthropometric, and psychological complications. Further complementary studies are needed to determine the least complicated MBS method.
