Hemodynamics before and after CGRP mAb.

	Baseline n = 18	Follow-up n = 18	p-value
Mean arterial blood pressure, mmHg	97.8 (14.0)	98.6 (13.2)	0.84
Peripheral vascular resistance, mmHg/L/min	0.65 (0.46–0.91)	0.61 (0.46–0.80)	0.64
CBFv, cm/s
Middle cerebral artery	51.6 (44.2–55.6)	57.2 (46.8–67.8)	0.27
Posterior cerebral artery	27.5 (23.8–37.6)	29.0 (23.9–32.5)	0.78
Pulsatility index
Middle cerebral artery	0.85 (0.73–0.92)	0.85 (0.79–0.93)	0.93
Posterior cerebral artery	0.86 (0.72–0.99)	1.00 (0.93–1.15)	0.003

Mean arterial pressure is normally distributed so is reported as mean (standard deviation). All other variables are non-normal so are reported as median (interquartile range). p-values were calculated by paired t-test or Wilcoxon signed rank sum test for normally and non-normally distributed variables, respectively. CBFv indicates cerebral blood flow velocity.
