*Minimum and maximum scores as measured in the studied group of stroke patients, numbers in brackets indicated minimum and maximum score for a given test; ** Interval between stroke onset and CT scan or cognitive assessment based on BCoS; A/KCT, Apples or Key Cancellation test; the maximum achievable score in these tests is 50 (AKCT accuracy). The cut-off for total numbers of target omissions i.e. accuracy score is 40/50. Spatial neglect is determined by whether patients miss targets (keys or full apples) on the left or right side of the page (asymmetry score calculated based on left- vs. right-side errors, AKCT/TA asymmetry score for targets, keys or full apples, indicating either left or right deficits); BL, bleed (haemorrhagic stroke); ISCH, ischaemic stroke; N/A, not applicable; Orient1, orientation measure assessing personal information; Orient2, orientation measure assessing time and space awareness; TE and VE; tactile and visual extinction tests, both tests consists of 4 unilateral left, 4 unilateral right and 8 bilateral trials, unilateral (uni) and bilateral (bilat) asymmetry scores are calculated based on left- vs. right-side misses.
