The dataset was randomly divided into training and validation cohorts in a 7:3 ratio. In the training cohort, logistic regression and least absolute shrinkage and selection operator regression analyses were used to identify predictive risk factors for infection in patients with AoCLD, and a simple nomogram was established. Two different cutoff values were determined to stratify infection risk in AoCLD patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The developed diagnostic model included six variables: cirrhosis, ascites, neutrophil count (N), total bilirubin, C-reactive protein (CRP) and blood sodium levels. The area under the receiver operating characteristic curve for the training and validation cohorts was 0.818 and 0.809, respectively, significantly higher than using CRP, procalcitonin or N alone. Additionally, in the training cohort, we set a low cutoff value of 0.2028, resulting in a sensitivity of 80.15%, specificity of 68.25% and a negative predictive value of 92.7% for rule-out diagnosis. A high cutoff value of 0.4045 results in a specificity of 90.1%, sensitivity of 52.7% and a positive predictive value of 64% for rule-in diagnosis. These cutoff values were validated in the validation cohort.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n
