Development and validation of a nomogram for arthritis: a cross-sectional study based on the NHANES.

Previous epidemiological studies have associated various body-related indicators with arthritis; however, the results have been inconclusive. Therefore, this research aimed to develop and validate a nomogram model for predicting the risk of arthritis using easily available indicators and to assess the model's predictive performance. Cross-sectional data were collected from 3660 participants in the 2021-2023 National Health and Nutrition Examination Survey.
