Associations between urinary iodine concentration and metabolically dysfunction-associated steatotic liver disease and advanced liver fibrosis in US adults: Evidence from the NHANES database 2001-2020

Given the potential significance of iodine in the development of metabolic dysfunction-associated steatotic liver disease (MASLD), this study aims to investigate the associations between urine iodine concentration (UIC), MASLD, and advanced liver fibrosis. Using data from the National Health and Nutrition Examination Survey. Logistic analysis generated odds ratios (OR) and 95% confidence intervals (CI) to assess the impact of iodine status. Restricted cubic spline (RCS) functions were applied to...
