failed to attain significanceP = .526
After pupil dilation, though changes in percentage of CD failed to attain significance in paired- T test ( P = .526) (Table 1 ), linear regression revealed thickness changes of SFChT that were positively correlated with changes in CD, with P = .046, adjusted R 2 = 0.126, correlation = 0.403 (Tables 4 and 5 ; Fig. 2 B).
