highly significantP < 0.001
The ANOVA detected highly significant main effects ( P < 0.001) of both Riboflavin Formulation and Time.
The ANOVA detected highly significant main effects ( P < 0.001) of both Riboflavin Formulation and Time.
While the difference did not reach statistical significance, a trend was observed (P = 0.095).
The ANOVA of the baseline-subtracted grades throughout UVA exposure showed a trend towards less degradation over time with the NaI-containing formulation, but the difference did not reach significance ( P = 0.12) Mean riboflavin concentration in the corneal stroma after the procedure and sacrifice was comparable in eyes treated with either formulation (NaI riboflavin: 49.7±11.3 μg/g; NaI-free riboflavin: 48.3 ± 8.2 μg/g) ( Figure 4A and Table S3 ).
