  1. a Some patients had more than one prior medical condition; b CAD (coronary artery disease)/MI (myocardial infarction); c Hemorrhage category is primarily spontaneous ICH, but also includes primary IVH and rare cases of SAH, EDH, SDH;d The original value was 0.02%, after rounding it was changed to 0.0%;
  2. e MHH-TMC = Memorial Hermann Hospital, Texas Medical Center, Houston; f Infarct does not include non–acute Infarct; g The sum of infarct patients in the stratified (or subgroup) analyses do not add up to 2572, because 83 patients were admitted to the stroke service from other units of MHH-TMC;h The sum of ICH patients in the stratified (or subgroup) analyses do not add up to 1198 because 11 patients were admitted to the stroke service from other units of MHH-TMC; i Door to needle (tPA) time includes off-label tPA treatment;j NA = Not applicable; k This includes patients treated with off-label thrombolysis.
