SD = Standard Deviation
*
p-values are paired t-test p-values comparing the pre-intervention mean score to the post-intervention mean score, unless otherwise noted
**
p-value is obtained using Wilcoxon Signed Rank test
Ɨ
HCCQ mean change in score not available as pre-intervention HCCQ assessed patient’s level of support from ophthalmologist while post-intervention HCCQ assessed patient’s level of support from glaucoma coach and are thus not directly comparable
