Change from Baseline to Week 12 for Each Outcome by Level of Confidence

	Change in CISS*		Change in NPC (cm)†		Change in PFV (Δ)‡
Level of Confidence	Mean	SD	Mean	SD	Mean	SD
Patients assigned to real therapy and who thought they were receiving real therapy
Not at all sure (n = 1)	−13.57	11.0	−10.93	7.1	17.63	10.4
A little sure (n = 6)
Somewhat sure (n = 4)	−5.88	10.3	−10.13	13.3	21.08	20.1
Pretty sure (n = 21)	−14.90	10.7	−8.29	4.5	20.52	13.6
Very sure (n = 23)	−17.13	14.1	−10.3	6.7	18.39	12.3
ANOVA results§	F = 1.00, P = 0.38		F = 0.68, P = 0.51		F = 0.15, P = 0.86

ANOVA results§	F = 0.24, P = 0.79		F = 1.54, P = 0.23		F = 0.39, P = 0.68

^*Negative change in CISS represents an improvement/decrease of symptoms.

^†Negative change in near point of convergence (NPC) represents an improvement/decrease in NPC.

^‡Positive change in positive fusional vergence (PFV) represents an improvement/increase in PFV.

^§After combining the “not at all.” “a little,” and “somewhat” sure categories due to the small number of patients in these groups.
