A: mean RNFL thickness for each group; : use simple linear regression analysis to get the coefficient determination of each group; F_A: use analysis of variance to prove the linear relationship between RNFL thickness and time. B: mean RNFL thinning thickness compared with baseline for each group; : use simple linear regression analysis to get the coefficient determination of each group; F_B: use analysis of variance to prove the linear relationship between RNFL thinning thickness and time.
