Figure 3: The measurement of central corneal thickness before and after epi-on CXL and epi-off CXL. *Wilcoxon test, the reduction of CCT in epi-off CXL: P = 0.009 at month 1, P = 0.007 at month 3, P = 0.01 at 6 months, P = 0.02 at 12 months, and P = 0.01 at 18 months and in epi-on CXL: P = 0.008 at month 1, P = 0.85 at month 3, P = 0.87 month 6, P = 0.51 at month 12, and P = 0.72 at 18 months. †Mann–Whitney U-test, the comparison of epi-on and epi-off CXL in terms of reduction in corneal thickness at 18 months, P = 0.02.
