Impact of blood lead and manganese levels on metabolic dysfunction-associated steatotic liver disease prevalence: insights from NHANES (2017-2020).

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
backgroundThe metabolic dysfunction-associated steatotic liver disease (MASLD) paradigm represents a significant departure from the previous nonalcoholic fatty liver disease (NAFLD) framework, offering a non-stigmatizing approach that enhances awareness and accelerates patient understanding. Our primary aim was to investigate the potential relationship between blood lead and manganese exposure and the onset of MASLD.
methodsUsing data from the National Health and Nutrition Examination Survey (NHANES) database spanning from 2017 to 2020, a cross-sectional study included 4,475 participants was performed to assess the relationship. The statistical analysis used throughout the study included multivariable linear regression and multiple logistic regression models, adjusted for potential confounders to ensure robust and reliable results. We applied a thorough multivariable analysis, examining various factors including age, sex, and ethnicity to enhance the robustness of our findings.
resultsEmploying linear regression models in our study, we observed a clear positive correlation between elevated levels of blood lead and manganese and Controlled attenuation parameter (CAP). Additionally, employing multiple logistic regression models for detailed analysis, we noted a significant increase in the likelihood of MASLD with higher levels of blood lead and manganese.
conclusionThe findings of this study strongly suggest a notable correlation between increased levels of blood lead and manganese with both CAP and the presence of MASLD. This study represents a population-based approach, enhancing the generalizability of the findings to the broader U.S. POPULATION:
