Twelve plasma cytokines and chemokines were quantified using a multiplex Luminex platform. Group differences were assessed using non-parametric tests with a two-stage false discovery rate (FDR) correction and age- and sex-adjusted residual models. Biomarker performance was evaluated by repeated Monte Carlo cross-validation using an ensemble feature-selection framework.\n                      <jats:italic>Post-hoc<\/jats:italic>\n                      power analyses were conducted to evaluate the robustness of subgroup comparisons.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Age, but not sex, differed across groups. After age- and sex-adjusted comparisons, six markers differed across groups. While recent infection exhibited a trend toward higher IL-23 and IL-12 concentrations compared to remote infection,\n                      <jats:italic>post-hoc<\/jats:italic>\n                      analysis revealed these subgroup differences had small effect sizes and were statistically underpowered. In the combined infection-vs.-TB comparison, IL-8 and CCL1 were higher in active TB, whereas IL-23, IL-12, IL-10, and IL-1ra were lower. Among multivariable models, XGBoost performed best (mean AUC 0.866), followed by the ensemble model (0.865) and random forest (0.861). Decision curve analysis suggested potential clinical utility across exploratory threshold probabilities, although no clinically validated operating point was predefined.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      Active TB exhibits a distinct peripheral cytokine pattern compared to\n                      <jats:italic>MTB<\/jats:italic>\n                      infection.
