  • The data are presented as number (%) for categorical variables. COPD indicates chronic obstructive pulmonary disease; GI, gastrointestinal; LACS, lacunar stroke; OCSP, Oxfordshire Community Stroke Project; PACS, partial anterior circulation stroke; POCS, posterior circulation stroke; TACS, total anterior circulation stroke.

  • a 0: no symptoms; 1: no significant disability despite symptoms, able to carry out all usual duties and activities; 2: slight disability, unable to perform all previous activities but able to look after own affairs without assistance; 3: moderate disability, requires some help but able to walk without assistance; 4: moderately severe disability, unable to walk without assistance and to attend to own bodily needs without assistance; 5: severe disability—bedridden, incontinent, and requiring constant nursing care and attention.
