Food Consumption and Weight Recurrence in Patients Undergoing Bariatric Surgery with a Minimum of 2 Years Post-surgery.
Observational study in Obesity surgery, 2023. 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
backgroundEating habits are one of the factors that directly affect weight recurrence after bariatric surgery, and therefore, this study assessed the association between food consumption and weight recurrence in patients who underwent bariatric surgery a minimum of 2 years.
methodsA cross-sectional observational study was conducted with patients who underwent bariatric surgery a minimum of 2 years through SUS, in the city of Palmas, Tocantins. Food consumption was assessed through two 24-h dietary recalls (R24). The foods were classified into groups by degree of processing following the NOVA classification system. Also, macronutrients and fiber contents were quantified. Anthropometric variables were evaluated and weight recurrence (WR) was defined as 15%.
resultsNinety-three (93) patients participated in the study, being 83.9% female, with mean age of 43.5 ± 9.13 years, mean post-surgery time of 4 years, and 58% present WR. A lower total energy consumption was found in patients without WR compared to those with WR (p = 0.05). Among the WR group, calories from processed foods (p = 0.00) and culinary ingredients (p = 0.05) were higher. However, carbohydrate consumption (percentage) was lower in the WR group (p = 0.04). A positive correlation was found between total energy (p = 0.03), processed foods (p = 0.03) and weight recurrence (p = 0.03).
conclusionWeight recurrence is associated with total daily energy intake, carbohydrates and food groups classified according to NOVA.
