Design outcomes

Primary

MeasureTime frame
CGRP concentrations in plasma and tear fluid in female migraine patients with and without COC

Secondary

MeasureTime frame
- CGRP concentrations in plasma and tear fluid in female migraine patients on COC compared with healthy female control subjects on COC. - CGRP concentrations in plasma and tear fluid in female migraine patients without COC compared with healthy female control subjects without COC. - CGRP concentrations in plasma and tear fluid in postmenopausal female migraine patients compared with premenopausal migraine patients - CGRP concentrations in plasma and tear fluid in postmenopausal female migraine patients compared with healthy female postmenopausal control subjects. - CGRP concentrations in plasma and tear fluid in male migraine patients compared with healthy male control subjects. - Evidence of a positive correlation between CGRP concentrations in plasma and tear fluid and estradiol concentrations in peripheral blood. - Evidence of a positive correlation between CGRP concentrations in plasma and tear fluid and progesterone concentrations in peripheral blood. - Evidence of a positive correlation between CGRP concentrations in plasma and tear fluid and testosterone concentrations in peripheral blood.
