Article Figures & Data
Figures
- FIG 1.
Scatterplot with best-fit line for the overall cohort shows a negligible correlation between the HIT-6 and Bern scores.
- FIG 2.
Subgroup analysis of subjects based on the time interval between brain MR imaging and HIT-6 administration. Scatterplots with best-fit lines show negligible correlations between the Bern score and the HIT-6 score in both the 0- to 3-month and 3- to 6-month subgroups.
- FIG 3.
Subgroup analysis of subjects based on symptom duration before brain MR imaging. Scatterplots with best-fit lines show weak correlation between Bern scores and HIT-6 scores for subjects with symptoms of 0- to 3-month duration and negligible correlation for subjects with symptoms of >3 months' duration.
- FIG 4.
Subgroup analysis of subjects who received or did not receive an EBP in the interval between brain MR imaging and HIT-6 administration. Scatterplots with best-fit lines show negligible correlation between HIT-6 and Bern scores in subjects who received an EBP and weak correlation in subjects who did not receive an EBP.
- FIG 5.
ROC curves depicting the ability of the Bern score to discriminate severe from not severe HIT-6 groups in both the overall cohort (AUC = 0.606; 95% CI, 0.347–0.864) and subgroup of subjects with brain MR imaging 0–3 months from completion of the HIT-6 (AUC = 0.635; 95% CI, 0.385–0.884). Bern scores performed poorly in both groups in discriminating clinical headache severity.
