Abstract
AIMS: To develop and validate a nomogram model based on clinical and laboratory parameters to predict the risk of metabolic dysfunction-associated fatty liver disease (MAFLD) in the early stage of type 2 diabetes. MATERIALS AND METHODS: We performed this study among 883 inpatients with new-onset type 2 diabetes, and the data were divided randomly into training and validation groups. The logistic regression method was used to identify the independent risk factors of MAFLD, and a nomogram was established according to the logistic regression analysis and these selected parameters. The discrimination, calibration, and clinical utility of the nomogram were measured by receiver operating characteristic curve analysis, calibration curves, and decision-curve analysis, respectively. RESULTS: Eight variables were identified and included in the nomogram (body mass index, alanine aminotransferase, triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting plasma glucose, urea nitrogen and serum uric acid). The value of the area under the receiver operating characteristic (ROC) curve was 0.898 for the training group and 0.92 for the validation group. The calibration plots indicated that this model had good accuracy, and the decision-curve analysis revealed high-clinical practicability of the nomogram. CONCLUSIONS: This study established a convenient and practical nomogram model, which can be used as an easy-to-use tool to evaluate the risk of MAFLD among patients with newly diagnosed T2DM.
