A multimodal mixed-methods approach for holistic insights in Roux-en-Y gastric bypass patients: Protocol for a patient-centered framework.

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
This protocol outlines the methodological approach for a multimodal mixed-methods study to investigate how social determinants impact the pre-and post-operative biochemical parameters and experiences of patients undergoing RYGB. It integrates quantitative and qualitative data from patients in a public hospital. Biochemical, anthropometric, and body composition data will be collected from 717 clinical records of patients who underwent RYGB from 2020 to 2024, with data extracted 30 days before and six months after surgery. Semi-structured interviews will be conducted with patients to explore their experiences and perspectives before and after surgery. To complement patient perceptions, a focus group will be conducted with nutritionists experienced in managing post-bariatric surgery patients to gather insights into nutritional challenges and post-surgical care strategies. The findings of this study will provide a comprehensive analysis of the short-term biochemical, anthropometric, and body composition changes in patients following RYGB surgery while shedding light on the social determinants that influence these outcomes.•This is one of the first multimodal mixed-methods studies in Brazil exploring both biochemical outcomes and lived experiences of RYGB patients in the public health system.•This study targets a vulnerable population by addressing non-communicable disease prevention through improved bariatric care.
