TABLE 4.

Treatment group difference at each time point

	Accommodative Amplitude (diopters)		Accommodative Facility (cycles per minute)
Time Point	Difference^† (95% CI)	P value	Difference^† (95% CI)	P value
Baseline	0.4 (−1.5 to 2.3)	0.99	0.1 (−1.7 to 2.0)	0.99
Week 4	3.5 (1.6 to 5.3)	0.0045	1.9 (0 to 3.7)	0.58
Week 8	4.5 (2.6 to 6.4)	<0.0001	4.0 (2.1 to 5.8)	0.0005
Week 12	3.8 (1.9 to 5.6)	0.0015	6.7 (4.9 to 8.5)	<0.0001
Week 16	3.9 (2.1 to 5.8)	0.0007	6.0 (4.1 to 7.8)	<0.0001

^†

Difference is computed as the mean value for the vergence/accommodative therapy group minus the mean value for the placebo therapy group at each time point.

CI = confidence interval.
