  • Univariable and multivariable mixed effects ordinal logistic regression analyses were done to test for the impact of several determinants on a reduction of mRS score and a decrease in disability. Variables that had a p<0.1 were included in the final multivariable model.

  • *The results after multiple imputation using chained equations to handle missing data.

  • CS/ESUS, cryptogenic stroke/embolic stroke of undetermined source; NIHSS, National Institutes of Health Stroke Scale; NLR, neutrophil–lymphocyte ratio; sICH, symptomatic intracranial haemorrhage; IV tPA, intravenous tissue plasminogen activator.
