We aimed to investigate the association between NPS and poor functional outcomes and test whether PhenoAge acceleration (PAA) mediates or jointly contributes to the relationships.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">This prospective cohort study included patients with acute ischemic stroke or transient ischemic attack from the CNSR\u2010III (Third China National Stroke Registry). The NPS (range, 0\u20134) was calculated based on serum albumin, total cholesterol, neutrophil\/lymphocyte ratio, and lymphocyte\/monocyte ratio, and categorized as low (0), medium (1 or 2), or high (3 or 4). Logistic regression was used to assess the association between NPS and poor functional outcomes (modified Rankin Scale [mRS] score, 2\u20136\/3\u20136). Mediation analyses were performed to explore the role of PAA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      A total of 7932 patients from the CNSR\u2010III were included in the analysis. High NPS was significantly associated with poor functional outcomes at 3 months (adjusted odds ratio [OR], 1.69 [95% CI, 1.13\u20132.52],\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.010 for mRS 3\u20136; adjusted OR, 1.31 [95% CI, 1.00\u20131.71],\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.048 for mRS 2\u20136). PAA partially mediated the observed association, with mediation proportions of 13.90% and 12.82% for mRS 3 to 6 and 2 to 6 at 3 months, respectively. Patients with both high NPS and PAA \u22650 had the highest risks of poor outcomes (adjusted OR, 2.16 [95% CI, 1.73\u20132.70] for mRS 3\u20136; adjusted OR, 1.51 [95% CI, 1.25\u20131.84] for mRS 2\u20136). Similar results were observed at 1 year. Incorporating combined NPS and PAA into the basic model improved predictive performance for short\u2010 and long\u2010term poor functional outcomes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">High NPS was associated with increased risk of poor functional outcomes at 3\u2010month and 1\u2010year follow\u2010ups in patients with acute ischemic stroke or transient ischemic attack.
