600 participants

Abstract

Investigators aim to compare the effect of zonisamide versus topiramate in migraine by assessing the absolute reduction in MMD in each group, the percentage of patients who achieved ≥ 50% reduction in the monthly headache days frequency compared to the baseline frequency

Conditions: Migraine.

Primary outcome: The change in migraine days per 28 days.

Enrollment: 600 participants.

How strong is the evidence?

Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 600 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
