Multivariable logistic regression was used to evaluate associations between six inflammatory indices (AISI, NLR, LMR, PLR, SII and SIRI) and MAFLD with or without liver fibrosis. Restricted cubic spline analysis assessed dose\u2013response relationships, while receiver operating characteristic (ROC) curves and random forest analysis evaluated diagnostic performance and variable importance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Multivariable logistic regression analysis showed that higher values of ln (AISI) and ln (SIRI) were significantly associated with increased odds of MAFLD, whereas ln (SII), ln (LMR) and ln (NLR) were not significantly associated with MAFLD (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u20090.05). In contrast, ln (PLR) was inversely associated with MAFLD. Among participants with liver fibrosis (LF), higher values of ln (AISI), ln (NLR) and ln (SIRI) were positively associated with MAFLD, whereas ln (PLR) remained inversely associated. No significant associations were observed for ln (LMR) or ln (SII) with MAFLD in the presence of LF. Among the evaluated inflammatory indices, AISI demonstrated the highest discriminatory performance for MAFLD (AUC\u2009=\u20090.752), whereas PLR showed the best performance for predicting liver fibrosis.
