Controlling Nutritional Status (CONUT) Score and Micronutrient Deficiency in Bariatric Patients: Midterm Outcomes of Roux-en-Y Gastric Bypass Versus One Anastomosis Gastric Bypass/Mini Gastric Bypass.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 papers, 2 of them syntheses that pooled 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.
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
backgroundTwo of the most common bariatric procedures performed worldwide are Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB). Comparative data regarding nutritional status are lacking and no previous study focus on malnutrition according to a validated score.
methodsRetrospective data from a single institution were reviewed. Anthropometric variables and nutritional data were assessed. The primary aim was to analyze and compare the nutritional status before and 3 years after RYGB vs OAGB using the controlling nutritional status (CONUT) score. The incidence of micronutrient deficiency and the remission of comorbidities in each group were defined as secondary outcomes.
resultsFifty-seven patients in each arm were enrolled. A 3-year mild malnutrition (CONUT score 2-3) was found in 38% and 37.05% in the RYGB and OAGB groups, respectively (p > 0.05). In terms of percentage of total weight loss (%TWL) and percentage of adjustable weight loss (%AWL), no differences were found between OAGB and RYGB groups. OAGB and RYGB patients had similar vitamin deficiencies. Anemia, hypoproteinemia, hypoalbuminemia, and hypocalcemia were comparable between groups. At 3-year follow-up, total protein and albumin values were similar between arms while prealbumin deficit was more frequent after OAGB than after RYGB. The rate of type 2 diabetes (87.5% in OAGB and 92% in RYGB), arterial hypertension (51.6% in OAGB and 58.3% in RYGB), and dyslipidemia (69.7% in OAGB and 78.6% in RYGB) remission was not significantly different between the two groups.
conclusionsPostoperative CONUT score, micronutrient deficiency, comorbidity remission, and improvement of anthropometric parameters 3 years postoperatively were comparable between RYGB and OAGB groups.
