Associations of prestroke physical activity with midline shift, IVH, NIHSS 0–4, mRS 0–3 and 90-day survival were calculated in binary logistic regression models. Results were obtained from imputed data.
*Adjusted for haematoma location and propensity scores based on age, sex, birthland, education, income, activities of daily living, living situation, smoking, alcohol, hypertension, hyperlipidemia, prior stroke or TIA, atrial fibrillation, diabetes mellitus, cardiac disease, heart failure, dementia, cancer, lipid-lowering drugs, antiplatelet drugs, antihypertensive drugs, non-vitamin k oral anticoagulants, warfarin and International Normalised Ratio.
†Adjusted for haematoma location, propensity scores and haematoma volume.
ICH, intracerebral haemorrhage; IVH, intraventricular haemorrhage; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; TIA, transient ischaemic attack.
