Mean Change From Baseline in Systolic and Diastolic Blood Pressure at Month 6 for Sumatriptan/Naproxen
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).

Treatment Difference in Systolic and Diastolic Blood Pressure Mean Changes From Baseline at 6 Months Between Sumatriptan/Naproxen and Naproxen
The calculation of baseline and post-baseline mean 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.

Mean Change From Baseline in Systolic and Diastolic Blood Pressure at Month 6 for Sumatriptan/Naproxen for the ITT Subpopulation of Participants Treating, on Average, <4 Migraines, 4-6 Migraines, >=4 Migraines, and >6 Migraines Per Month
The calculation of baseline and post-baseline mean BP (either systolic or diastolic) for each month (30-day period) is the average of all valid T-SMBP measurements. The subgrouping of the ITT population was created and examined to demonstrate the robustness of the results for the primary analysis.Descriptive statistics were calculated for baseline, month 6, and change from baseline to month 6. LSMeans and corresponding confidence intervals were based on MMRM analysis. LSMeans and corresponding confidence intervals were not calculated for \> 6 migraines/month group due to lack of convergence.
