Eligible diagnostic accuracy studies evaluated predictors of successful weaning in mechanically ventilated adults. The reference standard was successful liberation or extubation without reintubation or reinstitution of invasive ventilatory support within the study\u2010defined window, most commonly 48\u2009h. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies\u20102 (QUADAS\u20102) tool, and certainty was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty\u2010seven studies involving 2938 participants were included in the network meta\u2010analysis and evaluated eight predictors. Four additional eligible studies were not synthesised quantitatively because each evaluated a predictor reported in only one study. The extubation predictive score (ExPreS) was excluded from the connected network because it was evaluated in two single\u2010method studies without head\u2010to\u2010head comparisons, leaving seven predictors. Diaphragmatic excursion, diaphragm thickening fraction, and rapid shallow breathing index formed the core evidence network, and no significant threshold effect was detected. The network meta\u2010analysis showed no clear statistical superiority of any single predictor. Surface under the cumulative ranking curve (SUCRA) rankings suggested that mechanical ventilation duration and diaphragmatic excursion tended to rank higher for overall discrimination and specificity, whereas rapid shallow breathing index and negative inspiratory force ranked higher for sensitivity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Current evidence does not support a single universally optimal predictor.

Diaphragmatic excursion showed a relatively balanced diagnostic profile, whereas rapid shallow breathing index and negative inspiratory force ranked higher for sensitivity and mechanical ventilation duration ranked higher for overall discrimination and specificity; however, the certainty of evidence was generally low or very low.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:italic>Where and on whom will the research have an impact?<\/jats:italic>\n                      The findings are most relevant to critical care nurses, intensivists, respiratory therapists and multidisciplinary intensive care unit (ICU) teams caring for mechanically ventilated adults. They support a multidimensional weaning assessment strategy and may improve the safety and consistency of liberation decisions in adult critical care settings.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Implications for the Profession and\/or Patient Care<\/jats:title>\n                    <jats:p>The findings suggest that no single index should be used in isolation to guide weaning decisions. Diaphragmatic excursion may be a useful adjunct because of its relatively balanced diagnostic profile, but bedside decisions should continue to integrate ultrasound\u2010based measures, conventional respiratory indices, spontaneous breathing trial performance and overall clinical assessment to support safer, more individualised patient care.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Reporting Method<\/jats:title>\n                    <jats:p>This manuscript adhered to relevant Enhancing the QUAlity and Transparency Of health Research (EQUATOR) reporting guidance, specifically the Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses of Diagnostic Test Accuracy Studies and the Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses incorporating Network Meta\u2010analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>No Patient or Public Contribution<\/jats:title>\n                    <jats:p>Patients, service users, caregivers or members of the public were not involved in the design, conduct, analysis, interpretation or manuscript preparation for this systematic review and network meta\u2010analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial Registration<\/jats:title>\n                    <jats:p>The protocol for this systematic review was prospectively registered in PROSPERO (registration number CRD420261362977).
