Differential age‐effects and determinants of plasma NfL levels and GCL volume. Advancing age was associated with an exponential increase in plasma NfL levels (A), and an exponential decrease in GCL volume (B). Standardized estimates derived from a multivariable regression model, assessing the independent effect of each specified determinant, showed both similarities and differences between determinants of plasma NfL levels and GCL (C). Abbreviations: GFR, glomerular filtration rate; SBP, systolic blood pressure; BMI, body‐mass index; GCL, ganglion cell layer volume; NfL, neurofilament light chain. * q < 0.05, ** q < 0.001, *** q < 0.0001.
