Figure. Baseline NEI-VFQ-25 composite score vs HIT-6 score in IIHTT participants with newly diagnosed IIH.

Figure

Plot of the NEI-VFQ-25 composite score (y-axis) vs HIT-6 score (x-axis) at baseline in participants with newly diagnosed IIH in the IIHTT. The plot also shows the least-squares regression line. Higher HIT-6 scores, consistent with worse headache disability, were significantly associated with worse NEI-VFQ-25 composite scores (−0.75 per point increase on the HIT-6; 95% confidence interval: −1.00, −0.50; p < 0.001). HIT-6 = 6-item Headache Impact Test; IIH = idiopathic intracranial hypertension; IIHTT = Idiopathic Intracranial Hypertension Treatment Trial; NEI-VFQ-25 = National Eye Institute Visual Function Questionnaire–25.
