 Sites will identify, recruit, obtain consent for subjects and collect data using standard forms; these activities will be monitored remotely by the coordinating site. Data from the participating hospitals will be checked for heterogeneity, queried and subsequently pooled. Baseline patient characteristics and demographics, Hemphill and Essen predictive scores, NIHSS stroke severity score, functional status from the Barthel index and mRS score, and ICH volumetric assessments, will be presented as means, medians, or proportions, as appropriate. Eligibility and consent rates will be derived for each center.
