Absolute difference of TSS: maximum minus minimum TSS during the follow-up period; EST, estimate of regression coefficient; SE, standard error for the regression coefficient.

Since the baseline TSS values of GDxECC in progressing eyes‘n = 17) were all 100, the estimate of regression coefficient could not be calculated.
