Identification of nutritional risk factors and construction of a nomogram prediction model in AIDS patients

Objective: To investigate the nutritional risk factors in AIDS patients and to develop a nomogram prediction model. Methods: values reported. Based on the multivariable results, a nomogram prediction model was constructed using R version 4.2.1, and its discriminatory ability was evaluated by the area under the receiver operating characteristic curve (AUC). Results: = 0.002) were nutritional risk factors in AIDS patients. A nomogram model, constructed based on these variables, demonstrated good predictive performance, with an AUC of 0.959. At the optimal cutoff value of 0.7684, the sensitivity was 79.31% and the specificity was 97.53%. Conclusion: T-lymphocyte count, and low serum albumin are nutritional risk factors in AIDS patients. The nomogram model based on these three indicators shows acceptable predictive accuracy and may have potential value for the early clinical identification of nutritional risk, although further validation is needed.
