Figure 4. Scatter plots and fitted linear regression lines showing the relation between retinal thinning, follow-up time, and disease severity.

Figure 4

The regression lines represents fitted values for mean RNFL thinning or mean GCC thinning from baseline at each follow-up point; the areas between the dashed lines show the 95% confidence interval on the mean values. Accounting for age, the association between RNFL thinning from baseline and follow-up time (A) was significant (p=0.0075); the association between GCC thinning and follow-up time (B) was also significant (p=0.035). The association between RNFL thinning and disease severity tended to be significant (C, p=0.073 and E, p=0.137). There was no association between GCC thinning and disease severity (D and F).
