Demographics of (a) all non-encephalopathy stroke codes (non-EoSC) vs. encephalopathy only codes (EoSC) and (b) all non-encephalopathy stroke codes that were stroke positive (non-EoSC CVA +) vs. EoSC stroke positive (EoSC CVA+) using Definition 1 (positive findings in 1a, 1b, or 1c only). indicates statistical significance (p<.05).
