Figure 3

Mean fERG thresholds and slopes (± standard error) recorded at baseline and over the follow-up period in all patients. Note that mean decreased (i.e., sensitivity increased) from baseline already after three months of supplementation and then tended to stabilize. Mean fERG slope did not change significantly over time.
