NEFL and glaucoma: After controlling for covariates, there was no association between the number of preoperative classes of glaucoma medications and either log2-transformed AH NfL levels (t = 1.0, P = 0.32; Supplementary Fig. S2A) or log2-transformed serum NfL levels (t = 1.1, P = 0.26; Supplementary Fig. S2B).
