Association between BPF and OCT parameters in patients with RRMS.

<p>Patients (individual eyes) are labeled according to the history of optic neuritis (ON). Lines are derived from linear regression analyses with R² given in parentheses. Statistical significance level was calculated by Generalized Estimating Equation models controlling for the history of ON. A) Retinal nerve fiber layer thickness (RNFLT) vs. BPF (0.073, p = 0.019). B) Total macular volume (TMV) vs. BPF (0.113, p = 0.001).
