Median participant characteristics at screening as a function of bias type.

	Bias Type
	Where Only (n=7)	Aiming Only (n=5)	Aiming+Where (n=12)	p-value
Age	77.00 (10.00)	58.00 (19.00)	56.00 (15.50)	0.024
Gender	1 F/6 M	1 F/4 M	5 F/7 M	0.394
Days-post-stroke	40.00 (12.00)	39.00 (8.00)	32.00 (16.50)	0.730
Lesion Volume (cc)	106.3 (119.42)	99.76 (84.33)	120.20 (180.25)	0.171
Hemianopia	n = 0	n = 0	n = 3	0.180
CBS	10.00 (12.00)	9.00 (12.00)	12.00 (12.00)	0.528
CBS Spontaneous Recovery Rate	0.54 (0.51)	0.00 (0.25)	0.31 (0.54)	0.104
BIT	113.00 (42.00)	104.50 (43.50)	112.00 (79.50)	0.275
BIT Spontaneous Recovery Rate	0.54 (1.98)	0.43 (2.31)	1.41 (1.99)	0.367
Aiming Continuous	−5.15 (10.53)	4.81 (18.58)	9.38 (6.85)	< 0.001
Where Continuous	8.26 (18.23)	−9.70 (13.30)	6.67 (42.83)	0.003

Note: Cells reflect medians with interquartile range in parentheses. Days-post-stroke is the days-post-stroke at start of prism treatment. Higher scores on the CBS indicate more severe neglect. Lower scores on the BIT indicate more severe neglect. Aiming and Where continuous values in mm. p values refer to the results of Kruskal-Wallis tests, with the exception of that for gender and hemianopia, which refer to a chi-square test of independence.
