Traditional Brazilian dietary pattern as a factor associated with lower prevalence of dynapenic abdominal obesity in hemodialysis patients.

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
backgroundAbdominal dynapenic obesity, defined by the combination of excessive abdominal fat accumulation and reduced muscle strength, is an important marker for assessing nutritional status in hemodialysis patients. However, evidence on how dietary patterns influence this condition is limited. Therefore, this study aimed to explore factors associated with adherence to dietary patterns in patients who require hemodialysis and assess the link between these patterns and dynapenic abdominal obesity.
methodsThis is a cross-sectional study involving 996 patients requiring hemodialysis in Southeastern Brazil. Dietary patterns were identified using principal component analysis. Dynapenic abdominal obesity was defined by abdominal obesity and reduced muscle strength (measured by handgrip).
resultsOverall, three dietary patterns were identified: ovovegetarian; cafeteria; and traditional Brazilian. Higher adherence was associated with approximately twofold higher odds among individuals with an income above two minimum wages and those who engaged in physical activity. Men, patients undergoing hemodialysis for a longer duration, those who engaged in physical activity, and alcohol consumers were more likely to adhere to the cafeteria pattern, whereas older patients requiring hemodialysis and those without paid employment were less likely to adhere to this pattern. Individuals with more education adopted the traditional Brazilian pattern less often, but men and exclusive users of the public health system adhered to it more commonly. After adjustments for confounding variables, patients requiring hemodialysis with greater adherence to the traditional dietary pattern had 40.4% lower odds of dynapenic abdominal obesity (OR = 0.596, 95% CI 0.435-0.816, p < 0.001).
conclusionsThe findings underscore the complexity of dietary choices in patients undergoing hemodialysis, as these are influenced by a wide range of factors, and highlight that greater adherence to the traditional Brazilian dietary pattern was associated with lower odds of dynapenic abdominal obesity in this population.
