Review
Registration status and outcome reporting of trials published in core headache medicine journals.
To evaluate randomized controlled trial (RCT) registration and outcome reporting compliance in core headache medicine journals. ⋯ Only about a quarter of the articles published in the core headache medicine journals are compliant with trial registration, but compliance has increased over time. Selective reporting of outcomes remains a problem, and very few trials met all 3 reporting standards assessed in this study. Efforts to improve the quality of trial reporting in the headache literature should continue.
