Elevated platelet-to-lymphocyte ratio is associated with stroke-associated pneumonia in acute ischemic stroke: a retrospective cohort study
Background Stroke-associated pneumonia (SAP) is a common and serious complication of acute ischemic stroke (AIS) that substantially worsens clinical outcomes. The platelet-to-lymphocyte ratio (PLR), an accessible composite index derived from routine complete blood counts, may reflect post-stroke immune imbalance. Howev...
