The n values shows number of hospitals. IS indicates ischemic stroke; IV, intravenous; PAA, Performance Achievement Award; PSC, Primary Stroke Center; TPA, tissue‐type plasminogen activator.

^*P‐values are based on Pearson χ² tests for all categorical row variables or based on χ² rank‐based group means score statistics for all continuous/ordinal row variables (equivalent to Kruskal–Wallis test), indicating if there are differences in at least 1 hospital group.
