Analysis of the nutritional profile after endoscopic gastroplasty in the treatment of obesity.

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
backgroundEndoscopic gastroplasty (EG) has emerged as a promising technique for the treatment of obesity. However, data on the nutritional profile of patients after this surgical procedure are scarce in the literature.
aimsTo analyze the nutritional profile of patients who underwent EG for the treatment of obesity during the postoperative period.
methodsThis retrospective observational study investigated medical record data from a private healthcare service in Salvador, Bahia, where EG was performed EG. Epidemiological and laboratory data (total protein, albumin, calcium, zinc, vitamin B12, 25-hydroxyvitamin D, hemoglobin, glucose, glycated hemoglobin, ferritin, and iron) were collected before and after surgery over a 6-month period. A p-value>0.05 was considered statistically significant.
resultsTwenty-seven patients were analyzed, with a mean age of 43.8 (±13.3) years, of whom 88.9% were female. The patients' initial body mass index (BMI) was 35.31±8.7 kg/m2. Total weight loss was 10±5.7, and excess weight loss was 41.1±28.1. Preoperatively, iron deficiency was observed in 1 patient, vitamin B12 deficiency in 2 patients, 25-hydroxyvitamin D deficiency in 2 patients, zinc deficiency in 1 patient, calcium deficiency in 2 patients, and hyperglycemia in 4 patients. No consequences of these deficiencies were observed during follow-up. There was no correlation between BMI and laboratory data (p>0.05).
conclusionThe nutritional profile remained stable before and after EG, with sustained weight loss. CENTRAL MESSAGE: The surgical treatment of obesity currently involves laparoscopic surgery and bariatric therapeutic endoscopy, with technical variations that are increasingly adapted to individual patient circumstances. The most common laparoscopic options performed are sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and duodenal switch, with other emerging laparoscopic surgical techniques also aiming to induce malabsorption through manipulation of the small intestine. In primary obesity therapy, intragastric balloon implantation and endoscopic gastroplasty (EG) are minimally invasive endoscopic procedures. EG involves performing sutures on the anterior and posterior walls of the gastric body, creating a tubular configuration defined by the lesser curvature and angular incisure, as the greater curvature of the stomach is reduced. PERSPECTIVES: These findings show that the nutritional profile remained stable before and after EG in the short term (up to 6 months). Sustained weight loss was observed throughout the follow-up period, and body mass index and laboratory data before the procedure were not correlated. However, due to the reduced statistical power of this sample and the incompleteness of the data, the implications of EG for potential nutritional deficiencies in the management of obesity remain uncertain.
