Each cell indicates whether the demographic factor makes a patient more or less likely to be excluded for that particular reason. For example, for each year of age patients had an 8% increase in the odds of having a premorbid mRS≥3.
NIHSS is an estimate, grouped by mild, moderate or severe. Stroke type could be either ischaemic or haemorrhagic.
Grey cells indicate OR<1, p>0.05.
Bold cells indicate OR>1, p>0.05.
