a
P values calculated using ordinal linear regression or χ2 tests, as appropriate.
b
The definition used for symptomatic ICH was from the European-Australian Co-operative Acute Stroke Study III trial.16 Symptomatic ICH was defined as any apparently extravascular blood in the brain or within the cranium that was associated with clinical deterioration, as defined by an increase of 4 points or more in the score on the National Institute of Health Stroke Scale, or that led to death and that was identified as the predominant cause of the neurological deterioration.16
