Study	Sample size	Details of the type of stroke missed by the test as stated in the paper
Whiteley 2011	356	"Both the ROSIER and the FAST performed relatively poorly in identifying patients with posterior circulations strokes (18/37, 49% FAST positive and 19/37, 51% ROSIER positive)." p. 1008.
Lee 2015	312	TIA, thalamic infarction, posterior circulation stroke, middle cerebral artery infarction, intracranial hemorrhage, table 5, p. 471.
Jiang 2014	715	Not reported.
Nor 2005	160	"The false‐negative group included posterior circulation infarction (n = 5) and lacunar infarction (n = 2). The neurological signs in these cases were gait ataxia (n = 5), sensory deficits (n = 2), and one each of ophthalmoplegia, quadriparesis, and loss of consciousness. Most (six) of these false‐negative cases had mild deficits (NIHSS < 3), and would not have been clear candidates for thrombolytic therapy even if they had presented sufficiently early. The remaining patient had an NIHSS score of 24 and presented with drowsiness, gaze palsy, and quadriplegia." p. 371.
Jackson 2008	50	"Two patients with stroke were found to have a ROSIER score of 0, one was admitted unconscious with a large primary intracerebral hemorrhage and was wrongly scored and the second had a cerebellar infarct with no weakness, speech or visual field defect." p. 190.
