Primary Outcome Measures

Name	Time	Method
Mean Change From Baseline in Systolic and Diastolic Blood Pressure at Month 6 for Sumatriptan/Naproxen	Baseline and Month 6	The calculation of baseline and post-baseline mean blood pressure (BP) (either systolic or diastolic) for each month (30-day period) is the average of all valid Telephonic Self-Measured Blood Pressure (T-SMBP) measurements. T-SMBP technology is a method that allows the participant to self-measure BP outside the clinic using a BP monitor and transfer the data from their home to a central server. Change from baseline was calculated as the Month 6 value minus the Baseline value. Least squares mean and confidence intervals were based on mixed model repeated measures analysis (MMRM).
