Distribution of outcomes for patients with vestibular deficits by history of prior concussion

Prior Concussion	N (%)	% Vestibular Deficits	Test for Trend, P-Value	Median Days Until Resolution of Abnormal Gaze Stability (IQR)	Test for Trend, P-Value	Median Days Until Resolution of Abnormal Gait (IQR)	Test for Trend, P-Value
None	157 (64%)	75% (118/157)^*	0.004	51 (19,77)	0.217	58 (19,127)	0.657
One	54 (22%)	96% (52/54)		33 (17,77)		49 (28,104)
Two	22 (9%)	77% (17/22)		63 (32,83)		43 (28,79)
Three or More	13 (5%)	100% (13/13)		100 (54,152)		126 (118,184)

P-value <0.05, regression test for trend

IQR = interquartile range
