AIS: acute ischaemic stroke; NIHSS: National Institutes of Health Stroke Scale; OR: odds ratio; CI: confidence interval.
There was an association between shorter time from ictus to admission, higher NIHSS on admission, and high rate of rTPA treatment in acute ischaemic stroke patients between 50 and 80 years of age.
