(a) Spectral transmission of NDs. (b) Effect of testing conditions on CCT scores. This was estimated via linear regression with generalized estimating equations to account for repeated measurements (n = 18). Error bars represent 95% CI with Bonferroni correction (α = 0.05/18 = 0.0028) and correspond to 2.77 times the standard error of the mean CCT score for each group. *Statistically significant differences from baseline. LogCS scores are included above each bar of Figure 1b.
