NEURITIS
Patients were classified as having confirmed BP if their MRI findings confirmed the diagnosis of BP or as having nonidiopathic PFP if the initial diagnosis of BP was corrected based on MRI data. The 2 groups were compared to identify factors associated with nonidiopathic PFP at initial presentation and at the 1-month follow-up. The patients in the confirmed BP group were then subdivided according to whether their MRI findings were normal or pathological (hyperintensity in ≥1 portions of the facial nerve on the affected side). Finally, patients were grouped in terms of their time to MRI (<1 month or >1 month after initial presentation) to test the association with the presence of neuritis on MRI. Two-sided
