The sensitivity and specificity for triptan purchases to predict a positive treatment response. The figure presents the sensitivity (green) and specificity (blue) at different thresholds of minimum number of triptan-purchases, e.g. patients with ten or more triptan purchases had a sensitivity of 82% and specificity of 66% for prediction of positive treatment response (red line)
