Table 2.

BIT-C scores and percent improvement over time.

	Time 1	Time 2	Time 3 (Mid-Prisms)		Time 4 (Post-Prisms)		Time 7 (Last Follow-Up)
	Baseline BIT-C	Pre-Prism BIT-C	% Improve	d vs. 0	% Improve	d vs. 0	% Improve	d vs. 0
0 prisms	102.8 (36.1)	102.0 (46.5)	0.70% (1.8)		3.3% (4.0)		3.0% (2.4)
4–6 prisms	80.4 (52.4)	84.4 (54.7)	21.7% (28.0)	1.17	24.8% (38.5)	0.85	48.8% (62.3)	1.18
Matched 10 prisms	79.3 (41.4)	93.9 (43.0)	24.1% (29.1)	1.26	35.3% (82.3)	0.61	51.7% (115.0)	0.69

Note: Standard deviations in parentheses. Mean BIT-C (Times 1 and 2) and % improvement in BIT-C (from Pre-Prisms/Time 2 to Time 3, 4, and 7). d = Cohen’s d for each treatment group vs. the 0-prism control group. Participants completed a total of 7 assessments, with one week occurring between each assessment. Participants completed daily prism adaptation treatment sessions starting at time 2 and concluding prior to time 4.
