The results of multivariable linear regression model showed log-transformed GDF15 levels (β = –2.0, 95% CI: –3.7 to –0.2, t = –2.3, P = 0.027) but not log-transformed TGFB2 levels (β = –0.3, 95% CI: –8.0 to 7.5, t = –0.1, P = 0.945) predict worse mean deviations on VF testing after controlling for age, race, intraocular pressure (IOP), and diabetic status.
