  • Data are n (%) or median (IQR).

  • >90 d Days to walking 50 m unassisted was outside the three month censoring period for the median or 75% percentile; this parameter was therefore not able to be defined by the analysis. Three months ranged from 89 to 92 days depending on month of recruitment.

  • N/A Median days to walking 50 m unassisted unable to be calculated by the statistical analysis.

  • *Missing data for walking status at 3 months and number of days to walking 50 m unassisted for four participants.

  • †Missing data for one participant; did not consent for neuroimaging.

  • ICH, intracerebral haemorrhage; LACI, lacunar infarct; NIHSS, National Institutes of Health Stroke Scale; PACI, partial anterior circulation infarct; POCI, posterior circulation infarct; TACI, total anterior circulation infarct.
